Prerendering not working
Hi, I use nuxt with ddev and craft cms. So basically I run ddev npm run dev for starting the dev server -> Nuxt runs in docker on that url http://0.0.0.0:3000 and gets proxied by the nginx server. Therefor I am able to see the frontend on https://craft-nuxt-starter.ddev.site. When using the dev mode or build script I see no error and data fetching from the https://craft-nuxt-starter.ddev.site/v1/api/xxxx works perfectly.
My nuxt config looks like that:
But when I try to generate the site it throws following errors for every page:
The fetch from the prerender hook works but the api calls in the pages to get the data not.

Hi @Samuelreichoer. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
Based on the information provided in your question and the available knowledge sources, it appears you're encountering issues with prerendering in Nuxt 3. Let's address the problem and provide some potential solutions.
The error you're seeing (500 errors for every page during generation) suggests that there might be an issue with the API calls made during the prerendering process. This could be related to how Nuxt is trying to access your API endpoints during the static site generation.
Here are a few things to consider:
1. API Access During Prerendering:
When you run
nuxt generate
or use prerendering, Nuxt needs to be able to access your API endpoints. In your case, it seems that the prerender hook can access the API, but the individual page requests are failing.
2. Environment Variables:
Make sure that your environment variables, especially NUXT_PRIMARY_SITE_URL
, are correctly set for the build process. The API URL might need to be adjusted for the build environment.
3. Nitro Configuration:
You might need to adjust your Nitro configuration to handle both prerendering and API routes correctly. According to the Nuxt documentation on prerendering, you can use the nitro
config in your nuxt.config.ts
to specify prerender options:
This configuration tells Nitro to crawl links for prerendering, start from the root route, and ignore the /api
routes.
4. Route Rules:
You can also use routeRules
to specify which routes should be prerendered. As mentioned in the Nuxt documentation on prerendering, you can do:
5. Debugging:
To get more information about what's causing the 500 errors, you can try to log more context of prerendering errors. This feature was added in a recent Nuxt update, as mentioned in this GitHub pull request. Make sure you're using the latest version of Nuxt to benefit from improved error logging during prerendering.
6. API Timing:
Ensure that your API is fully ready and accessible when the prerendering process starts. If there's a timing issue where the API isn't ready when Nuxt tries to access it, this could cause the 500 errors you're seeing.
If these suggestions don't resolve the issue, you might need to investigate further by examining the full error logs and potentially setting up additional debugging in your Nuxt application to trace where exactly the API calls are failing during the prerender process.

Can I somehow use a whole env file for the npm command
@kapa.ai does the npm run build comman respect the env file in the folder?
Let me check the knowledge base for you again. One moment! :books:
----------------------
Yes, the
npm run build
command in Nuxt 3 does respect the .env
file in your project folder, but there are some important details to consider:
1. Dev, Build, and Generate Time:
According to the Nuxt documentation on .env files, Nuxt CLI has built-in dotenv support when running nuxi build
(which is what npm run build
typically runs). The documentation states:
"In addition to any process environment variables, if you have a .env
file in your project root directory, it will be automatically loaded at dev, build and generate time. Any environment variables set there will be accessible within your nuxt.config
file and modules."
2. Location of .env file:
The .env
file should be located in the root directory of your Nuxt project for it to be automatically loaded.
3. Custom .env files:
If you want to use a different file, such as .env.production
, you can do so by passing the --dotenv
flag:
4. Production Deployment:
It's important to note that while the .env
file is respected during the build process, it is not used in production runtime. As stated in the documentation:
"After your server is built, you are responsible for setting environment variables when you run the server. Your .env
files will not be read at this point."
5. Runtime Config:
For values that need to be accessible in your application code, you should use Runtime Config instead of plain env variables.
Remember to add your .env
file to your .gitignore
to avoid pushing sensitive information to your repository.
In summary, yes, npm run build
will respect your .env
file during the build process, but you need to ensure proper configuration for production deployment.

@kapa.ai how can i debugg why the prerendering is not working
Let me check the knowledge base for you again. One moment! :books:
----------------------
To debug why prerendering is not working in your Nuxt application, you can follow these steps:
1. Enable more detailed error logging:
As mentioned in a recent Nuxt update, there's improved error logging for prerendering. Make sure you're using the latest version of Nuxt to benefit from this. The GitHub pull request states:
"This PR does a couple of things:
1. it prints out the stack trace of errors when prerendering
2. it prints out the full error message on the console when prerendering + in production as opposed to the sanitised 'internal server error' which is a bit cryptic"
2. Use the
nitro.prerender.crawlLinks
option:
In your nuxt.config.ts
, add the following:
This will enable more verbose logging during the prerendering process, as mentioned in the Nuxt documentation on prerendering.
3. Check your API responses:
Make sure your API is returning the expected data during the prerendering process. You can add console logs in your API routes or in the components that fetch data to see what's being returned.
4. Use the routeRules
configuration:
You can use routeRules
to explicitly define which routes should be prerendered and which should not. This can help isolate the issue:
This is explained in the Nuxt documentation on prerendering.
5. Check environment variables:
Ensure that your environment variables are correctly set for the build process. You can add console logs in your nuxt.config.ts
to verify the values of critical environment variables.
6. Use the --dotenv
flag:
If you suspect issues with environment variables, you can explicitly specify which .env
file to use:
This ensures that the correct environment variables are being used during the prerendering process.
7. Examine the Nitro logs:
When running nuxi generate
, pay close attention to the Nitro logs. They often provide valuable information about the prerendering process, including which routes are being generated and any errors encountered.
By implementing these debugging strategies, you should be able to gather more information about why prerendering is failing in your Nuxt application. The key is to enable verbose logging and carefully examine the output for any clues about what might be going wrong during the prerendering process.

Let me check the knowledge base for you again. One moment! :books:
----------------------
This error message indicates that your Nuxt application is running out of memory during the static site generation process when using the
nuxi generate
command. This is a common issue when dealing with large applications or when generating a significant number of pages. Let's look at some potential solutions:
1. Increase Node.js memory limit:
You can increase the memory limit for Node.js by using the --max-old-space-size
flag. Try running the command like this:
This sets the memory limit to 8GB. Adjust the number based on your system's available memory.
2. Optimize your application:
Look for memory leaks or inefficient code in your application. Large data sets, recursive functions, or excessive API calls during the generation process can lead to high memory usage.
3. Generate in chunks:
If you have a large number of pages, consider generating them in smaller batches. You can use the routeRules
configuration in your nuxt.config.ts
to specify which routes to prerender:
4. Use nitro.prerender
options:
You can configure the prerendering process in your nuxt.config.ts
:
This reduces concurrency and adds an interval between page generations, which can help with memory usage.
5. Update dependencies:
Ensure you're using the latest versions of Nuxt and its dependencies, as memory management improvements are often included in updates.
6. Monitor memory usage:
Use tools like node --inspect
along with Chrome DevTools to monitor memory usage and identify potential memory leaks.
7. Consider server-side rendering:
If static site generation is consistently problematic due to the size of your application, you might want to consider using server-side rendering instead.
If these solutions don't resolve the issue, you may need to further investigate your application's structure and data fetching processes to identify the root cause of the high memory usage.

Use craft query is just a url builder and useasyncdata under the hood
Let me check the knowledge base for you again. One moment! :books:
----------------------
Based on the information provided in your question and the knowledge sources available, I can offer some suggestions on how to handle errors differently in your Nuxt application, particularly when using
useCraftQuery
which utilizes useAsyncData
under the hood.
Here's a more robust way to handle errors in this scenario:
1. Use createError
more specifically:
Instead of always throwing a 500 error, you can be more specific about the error type. For example:
This approach uses the error information from the query result to create a more informative error.
2. Use showError
for client-side errors:
As mentioned in the Nuxt documentation on error handling, you can use showError
for client-side errors:
3. Use <NuxtErrorBoundary>
:
For more granular error handling, you can wrap your component with <NuxtErrorBoundary>
. This allows you to handle errors locally within a component:
This approach is described in the Nuxt documentation on error handling.
4. Use useError
composable:
You can use the useError
composable to handle errors more flexibly:
This approach allows you to handle errors without immediately throwing them, giving you more control over the error handling process.
Remember, the best error handling approach depends on your specific use case and how you want errors to be managed in your application. These suggestions provide more flexibility and granularity in error handling compared to the original code.

----------------------
I understand you're still encountering issues with prerendering and not getting a detailed error message. Let's try to address this problem with some additional debugging steps.
1. Enable more verbose logging:
Add the following to your
nuxt.config.ts
file to enable more detailed logging:
This should provide more detailed logs during the prerendering process.
2. Use the --trace-warnings
flag:
Run your generate command with the --trace-warnings
flag to get more detailed stack traces:
3. Check for unhandled rejections:
Add the following code to your nuxt.config.ts
to catch unhandled promise rejections:
4. Use a custom error page:
Create an error.vue
file in your project root to catch and display errors:
This custom error page might help capture more details about the error.
5. Check your API responses:
If your root page is fetching data from an API, ensure that the API is accessible and returning the expected data during the prerendering process. You can add console logs in your API routes or in the components that fetch data to see what's being returned.
6. Isolate the issue:
Try commenting out parts of your root page component to identify which part is causing the error. This can help narrow down the source of the problem.
7. Update Nuxt and dependencies:
Ensure you're using the latest versions of Nuxt and its dependencies, as there have been recent improvements in error logging for prerendering.
If after trying these steps you're still not getting a more detailed error message, you might need to manually add more logging throughout your application, especially in any asynchronous operations or data fetching logic on your root page.
Remember, the root cause of the 500 error could be in your application code, so carefully review any custom server-side logic, API calls, or data processing that happens during the render of your root page.

Let me check the knowledge base for you again. One moment! :books:
----------------------
The output you're seeing indicates two main issues:
1. A warning about insecure TLS connections due to disabling certificate verification.
2. A 500 error occurring during the prerendering of your root route ('/').
Let's address these issues:
1. TLS Certificate Verification Warning:
The warning about
NODE_TLS_REJECT_UNAUTHORIZED
being set to '0' is a security concern. This setting disables SSL/TLS certificate verification, making your connections insecure. It's likely you've set this environment variable to bypass SSL certificate issues, possibly with a self-signed certificate.
As mentioned in the Nuxt documentation on $fetch, if you're using a self-signed certificate in development, you need to set this environment variable. However, it's not recommended for production use.
For development, you can set this in your script in package.json
:
For production, you should use properly signed certificates instead.
2. 500 Error on Root Route:
The 500 error on your root route suggests that there's an issue with the content or data fetching on this page. To debug this:
a. Enable more verbose logging in your nuxt.config.ts
:
b. Check for any API calls or data fetching in your root page component. Ensure these are working correctly and handling errors appropriately.
c. If you're using useCraftQuery
or similar on your root page, make sure it's properly handling errors:
d. Create a custom error page (error.vue
in your project root) to capture more error details:
Remember, the root cause of the 500 error is likely in your application code, particularly in the root page component or any server-side logic it depends on. You may need to add more console.log statements throughout your code to pinpoint where the error is occurring.
Nuxt Documentation on Error Handling
Nuxt Documentation on Prerendering
If you're still unable to resolve the issue after these steps, you might need to provide more details about your root page component and any data fetching or API calls it makes.

Let me check the knowledge base for you again. One moment! :books:
----------------------
Thank you for providing the error output. This stack trace indicates that there's an issue occurring during the execution of
useAsyncData
in your Nuxt application, specifically in a file that seems to be handling dynamic routes (given the ...slug
in the file name).
Here's an analysis of the error and some suggestions:
1. The error is occurring in the asyncData.refresh
or asyncData.execute
function, which is part of the useAsyncData
composable.
2. It appears to be happening during the initial fetch of data for a page.
3. The error is likely related to how you're handling data fetching or error handling in your component.
To address this issue, try the following:
1. Review your error handling:
In the component where you're using useAsyncData
or useCraftQuery
, make sure you're properly handling errors. For example:
2. Check for undefined values:
Ensure that all the values you're using in your data fetching (like uri.value
or currentSite.value.handle
) are defined before using them.
3. Add more detailed logging:
Add more console.log
statements in your component to track the flow of execution and identify where exactly the error is occurring.
4. Use a try-catch block:
Wrap your data fetching logic in a try-catch block to catch and log any errors that might be occurring:
5. Check your API endpoints:
Ensure that the API endpoints you're fetching from are accessible and returning the expected data during the prerendering process.
6. Review your nuxt.config.ts
:
Make sure your Nuxt configuration, especially related to prerendering and API handling, is correct.
If you're still encountering issues after trying these steps, you might need to provide more context about your component code, particularly the part where you're using useAsyncData
or useCraftQuery
.
Nuxt Documentation on Error Handling
Nuxt Documentation on useAsyncData
Remember, the key to resolving this issue is to identify where exactly in your data fetching process the error is occurring, and then handle that specific scenario appropriately.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
----------------------<@1065266379382587422> Kapa.ai is still learning and improving, please let me know how I did by reacting below.
@kapa.ai that's the code of useCraftQuery
import type { ElementType } from 'js-craftcms-api'
import { useCraftUrlBuilder } from 'vue-craftcms'
import { useAsyncData } from '#imports'
function fetchFn(url: string) {
return useAsyncData(
craftcms:${url}
, () => $fetch(url))
}
export function useCraftQuery<T extends ElementType>(elementType: T) {
const queryBuilder = useCraftUrlBuilder(elementType)
return {
...queryBuilder,
one() {
const url = queryBuilder.buildUrl('one')
return fetchFn(url)
},
all() {
const url = queryBuilder.buildUrl('all')
return fetchFn(url)
},
}
}Let me check the knowledge base for you again. One moment! :books:
----------------------
Thank you for providing the code for
useCraftQuery
. This helps in understanding how the query is being built and executed. Based on this code and the previous error output, I can offer some insights and suggestions:
1. Error Handling:
The current implementation doesn't include explicit error handling. When useAsyncData
encounters an error, it's not being caught or processed within useCraftQuery
. To improve error handling, you could modify the fetchFn
like this:
2. URL Building:
Ensure that useCraftUrlBuilder
is correctly building the URL. If the URL is malformed, it could lead to fetch errors. You might want to add some logging to see what URL is being generated:
3. Async Data Key:
The key used in useAsyncData
(craftcms:${url}
) might be causing issues if the URL is very long or contains special characters. Consider using a more concise key or hashing the URL:
4. Error Propagation:
Make sure that errors from useAsyncData
are being properly propagated to the calling component. In your component where you use useCraftQuery
, handle potential errors:
5. API Endpoint Accessibility:
Ensure that the API endpoint you're trying to reach is accessible during the prerendering process. If it's not, you might need to adjust your server configuration or use a different approach for prerendering.
6. Debugging:
Add more detailed logging throughout useCraftQuery
to track the flow of execution and identify where exactly the error is occurring.
Given the error stack trace you provided earlier, it seems the issue is occurring during the execution of useAsyncData
. This could be due to network issues, API errors, or problems with the data being returned.
To further debug this, you might want to add more detailed logging in your component where you're using useCraftQuery
, and also consider adding a global error handler in your Nuxt config to catch and log any unhandled errors during the prerendering process.

If you implement these suggestions and still encounter issues, please provide more details about how you're using useCraftQuery
in your component and any new error messages you might see.

@kapa.ai Okey ich habe jetzt den fehler gefunden, der nitro host ist localhost und nicht wie gewünscht 'https://craft-nuxt-starter.ddev.site/' wie stelle ich das um?
Let me check the knowledge base for you again. One moment! :books:
----------------------
Ich verstehe, dass Sie den Fehler gefunden haben und dass der Nitro-Host auf "localhost" eingestellt ist, anstatt auf "https://craft-nuxt-starter.ddev.site/", wie Sie es möchten. Um dies zu ändern, können Sie die folgenden Schritte in Ihrer Nuxt-Konfiguration vornehmen:
1. Öffnen Sie Ihre
nuxt.config.ts
Datei.
2. Fügen Sie die runtimeConfig
Option hinzu oder aktualisieren Sie sie, wenn sie bereits vorhanden ist:
3. Stellen Sie sicher, dass Sie die Umgebungsvariable NUXT_PUBLIC_API_BASE
in Ihrer .env
Datei oder in Ihren Umgebungsvariablen setzen:
4. In Ihrem Code, wo Sie API-Aufrufe machen, verwenden Sie die runtimeConfig
anstelle von hartcodierten URLs:
5. Wenn Sie speziell den Nitro-Server konfigurieren möchten, können Sie auch die nitro
Option in Ihrer nuxt.config.ts
hinzufügen:
Diese Konfiguration leitet alle Anfragen an /api
während der Entwicklung an Ihre ddev-Site weiter.
6. Für die Produktionsumgebung stellen Sie sicher, dass Sie die entsprechenden Umgebungsvariablen auf Ihrem Hosting-Server setzen.
Diese Änderungen sollten Ihnen helfen, den gewünschten Host "https://craft-nuxt-starter.ddev.site/" anstelle von "localhost" zu verwenden.
Denken Sie daran, nach diesen Änderungen Ihren Nuxt-Server neu zu starten, damit die neuen Konfigurationen übernommen werden.

Nein nitro läuft auf local host somit ist dieses composable
export function useCraftFullUrl() {
const route = useRoute()
const fullUrl = ref(import.meta.server ? useRequestURL().href : window.location.href)
watch(route, () => {
fullUrl.value = import.meta.server ? useRequestURL().href : window.location.href
})
return fullUrl
}
falsch und kann nicht den richtigen url herausfinden und dann nicht den richtigen query bauen

Let me check the knowledge base for you again. One moment! :books:
----------------------
Ich verstehe Ihr Problem. Sie haben Recht, dass das
useCraftFullUrl
Composable in diesem Fall nicht korrekt funktioniert, da es auf useRequestURL()
oder window.location.href
basiert, die beide auf den lokalen Nitro-Server verweisen und nicht auf Ihre gewünschte URL "https://craft-nuxt-starter.ddev.site/".
Um dieses Problem zu lösen, können wir das Composable anpassen, damit es die korrekte Basis-URL verwendet. Hier ist ein Vorschlag, wie Sie das Composable umschreiben können:
Dieses überarbeitete Composable macht Folgendes:
1. Es verwendet useRuntimeConfig()
, um die Basis-URL aus der Konfiguration zu erhalten.
2. Falls keine Konfiguration vorhanden ist, wird die Standard-URL "https://craft-nuxt-starter.ddev.site/" verwendet.
3. Es kombiniert die Basis-URL mit dem aktuellen Routenpfad, um die vollständige URL zu erstellen.
4. Es aktualisiert die URL, wenn sich die Route ändert.
Um dies zu verwenden, müssen Sie sicherstellen, dass Sie die runtimeConfig
in Ihrer nuxt.config.ts
korrekt eingerichtet haben:
Und setzen Sie die Umgebungsvariable NUXT_PUBLIC_API_BASE
in Ihrer .env
Datei oder in Ihren Umgebungsvariablen:
Mit dieser Anpassung sollte Ihr useCraftFullUrl
Composable nun die korrekte URL zurückgeben, unabhängig davon, ob es auf dem Server oder dem Client ausgeführt wird, und es sollte die richtige Basis-URL für Ihre Queries verwenden.
Nuxt Documentation on Runtime Config
Nuxt Documentation on Composables
Denken Sie daran, dass Sie möglicherweise auch andere Teile Ihres Codes anpassen müssen, die von der URL-Generierung abhängen, um sicherzustellen, dass überall die korrekte Basis-URL verwendet wird.

@kapa.ai can i somehow check if i am in prerendering and use another method to determine the url?
Let me check the knowledge base for you again. One moment! :books:
----------------------
Yes, you can check if you're in the prerendering process and use a different method to determine the URL. Nuxt provides a way to detect if the current context is prerendering. Here's how you can modify your
useCraftFullUrl
composable to handle this:
This modified composable does the following:
1. It uses useNuxtApp()
to access the Nuxt application instance.
2. It checks if we're in the prerendering process by looking at nuxtApp.isHydrating
and nuxtApp.payload.prerenderedAt
. This is based on the Nuxt documentation on useNuxtApp.
3. If we're prerendering, it uses the baseUrl from the runtime config combined with the current route path.
4. If we're on the server but not prerendering, it uses useRequestURL()
.
5. If we're on the client, it uses window.location.href
.
This approach should give you the correct URL in all contexts, including during prerendering.
Remember to keep your nuxt.config.ts
and .env
file configured as mentioned in previous responses:
This solution should allow you to get the correct URL during prerendering, server-side rendering, and client-side rendering.

@kapa.ai Transform failed with 1 error:
/Users/samuel/Documents/Private-Projekte/00-repos/nuxt-craftcms/src/runtime/composables/useComposables.ts:13:2: ERROR: Unexpected "const" the error happens at the getFullUrl var
Let me check the knowledge base for you again. One moment! :books:
----------------------
Thank you for providing the specific error message. It seems the issue is related to the declaration of the
getFullUrl
function. Let's modify the code to resolve this syntax error. Here's a corrected version of the useCraftFullUrl
composable:
The main change here is that we've replaced the arrow function syntax const getFullUrl = () => { ... }
with a regular function declaration function getFullUrl() { ... }
. This should resolve the "Unexpected const" error you were encountering.
This modification maintains the functionality of the composable while addressing the syntax issue. The getFullUrl
function is now declared using the function keyword, which should be compatible with the transformation process in your Nuxt project.
If you're still encountering issues after this change, please let me know, and we can further investigate the problem. Make sure that all the imports at the top of the file are correct and that you're using a version of Nuxt that supports this syntax.
