Why is it when I refresh the page I get api calls error?

This is the code on me dashboard.vue

<template>
    <div class="flex flex-col min-h-screen">
        <DashboardHeader :user="user" />
        <main class="flex-grow w-full mx-auto">
            <slot />
        </main>
        <Footer />
    </div>
</template>
<script setup lang="ts">
const { user, getCurrentUser } = useAuth();
getCurrentUser();
</script>

        </main>
        <Footer />
    </div>
</template>
<script setup lang="ts">
const { user, getCurrentUser } = useAuth();
getCurrentUser();
</script>

                method: "GET",
                headers: sessionHeader,
            });

            if (data.body && "user" in data.body) {
                user.value = data.body.user;
            }
        } catch (err) {
            console.log(err);
        }

Hi @o.m. 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 knowledge sources available, it appears that you're experiencing an issue with API calls when refreshing the page in a Nuxt application. This problem is likely related to how data fetching and caching work in Nuxt 3. Let me explain the possible reasons and suggest some solutions: 1. Caching behavior: By default, Nuxt caches the results of data fetching composables like useFetch and useAsyncData. When you refresh the page, Nuxt might be using the cached data instead of making a new API call. This can lead to errors if the cached data is stale or if the API is expecting fresh authentication. 2. Server-side rendering (SSR) vs. Client-side rendering: The error might occur because the API call is being made differently on the server-side compared to the client-side, especially if you're using authentication headers that are not available during SSR. To address these issues, you can try the following solutions: 1. Use useFetch with a unique key: Instead of using $fetch directly, wrap your API call in useFetch and provide a unique key. This will help Nuxt manage the caching more effectively:

const { data, error } = await useFetch("/api/auth/user", {
  key: `user-${Date.now()}`, // Unique key
  headers: sessionHeader,
});

if (data.value && "user" in data.value) {
  user.value = data.value.user;
}

const { data, error } = await useFetch("/api/auth/user", {
  key: `user-${Date.now()}`, // Unique key
  headers: sessionHeader,
});

if (data.value && "user" in data.value) {
  user.value = data.value.user;
}

2. Disable caching: If you always want fresh data, you can disable caching by setting cache: false in the useFetch options:

const { data, error } = await useFetch("/api/auth/user", {
  key: 'user',
  cache: false,
  headers: sessionHeader,
});

const { data, error } = await useFetch("/api/auth/user", {
  key: 'user',
  cache: false,
  headers: sessionHeader,
});

3. Use refreshNuxtData: If you need to manually refresh the data, you can use the refreshNuxtData utility:

await refreshNuxtData('user')

await refreshNuxtData('user')

4. Handle server-side vs. client-side: Ensure that your sessionHeader is available on both server and client. You might need to use useRequestHeaders to properly handle headers during SSR:

const headers = useRequestHeaders(['cookie'])

const headers = useRequestHeaders(['cookie'])

5. Use useLazyFetch: If you want to fetch data only on the client-side, you can use useLazyFetch:

const { data, error, refresh } = useLazyFetch("/api/auth/user", {
  headers: sessionHeader,
});

const { data, error, refresh } = useLazyFetch("/api/auth/user", {
  headers: sessionHeader,
});

These suggestions are based on the information provided in the Nuxt 3 Data Fetching documentation (https://nuxt.com/docs/getting-started/data-fetching) and useFetch documentation (https://nuxt.com/docs/api/composables/use-fetch). Remember to handle loading and error states appropriately in your component when using these data fetching methods. If you're still experiencing issues after trying these solutions, you might need to provide more details about the specific errors you're encountering and the version of Nuxt you're using. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai this is the error I get

[GET] "/api/auth/user": 404 User not found

[GET] "/api/auth/user": 404 User not found

kapa.ai•15h ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the error message you've provided, it seems that the API endpoint /api/auth/user is returning a 404 "User not found" error. This suggests that the issue is not directly related to Nuxt's data fetching or caching mechanisms, but rather to the API itself or the authentication state. Let's explore some possible reasons and solutions: 1. Authentication State: The most likely cause is that the user's authentication state is not being properly maintained or passed to the API. This could happen if: - The user's session has expired - The authentication token is not being sent correctly in the request headers - The server-side session management is not working as expected 2. API Route Implementation: There might be an issue with how the /api/auth/user route is implemented on your server. To address this issue, you can try the following: 1. Check Authentication Headers: Ensure that you're sending the correct authentication headers with your request. You can log the headers to verify:

   const { data, error } = await useFetch("/api/auth/user", {
     headers: sessionHeader,
     onRequest({ request, options }) {
       console.log('Request headers:', options.headers)
     },
   });

   const { data, error } = await useFetch("/api/auth/user", {
     headers: sessionHeader,
     onRequest({ request, options }) {
       console.log('Request headers:', options.headers)
     },
   });

2. Verify Session State: Make sure your session is still valid. You might need to implement a session refresh mechanism if it's expiring too quickly. 3. Handle Unauthenticated State: In your getCurrentUser function, add logic to handle the 404 error specifically:

   const getCurrentUser = async (): Promise<void> => {
     try {
       const { data, error } = await useFetch("/api/auth/user", {
         headers: sessionHeader,
       });
if (error.value) {
         if (error.value.statusCode === 404) {
           console.log("User not authenticated");
           // Redirect to login page or clear user state
           user.value = null;
           // You might want to use navigateTo('/login') here
         } else {
           console.error("Error fetching user:", error.value);
         }
         return;
       }

       if (data.value && "user" in data.value) {
         user.value = data.value.user;
       }
     } catch (err) {
       console.error("Unexpected error:", err);
     }
   };

   const getCurrentUser = async (): Promise<void> => {
     try {
       const { data, error } = await useFetch("/api/auth/user", {
         headers: sessionHeader,
       });
if (error.value) {
         if (error.value.statusCode === 404) {
           console.log("User not authenticated");
           // Redirect to login page or clear user state
           user.value = null;
           // You might want to use navigateTo('/login') here
         } else {
           console.error("Error fetching user:", error.value);
         }
         return;
       }

       if (data.value && "user" in data.value) {
         user.value = data.value.user;
       }
     } catch (err) {
       console.error("Unexpected error:", err);
     }
   };

4. Check API Implementation: Verify that your server-side API route for /api/auth/user is correctly implemented and is able to identify the user based on the session or token you're sending. 5. Use Error Handling in Component: In your dashboard.vue, you can add error handling:

   <script setup lang="ts">
   const { user, getCurrentUser } = useAuth();
   const { error } = await getCurrentUser();

   if (error.value) {
     // Handle the error, maybe redirect to login
     navigateTo('/login');
   }
   </script>

   <script setup lang="ts">
   const { user, getCurrentUser } = useAuth();
   const { error } = await getCurrentUser();

   if (error.value) {
     // Handle the error, maybe redirect to login
     navigateTo('/login');
   }
   </script>

6. Implement Auth Middleware: Consider using Nuxt middleware to check authentication status before rendering pages that require authentication. This can help prevent the 404 errors by redirecting unauthenticated users:

   // middleware/auth.ts
   export default defineNuxtRouteMiddleware((to, from) => {
     const { user } = useAuth();
     if (!user.value) {
       return navigateTo('/login');
     }
   });

   // middleware/auth.ts
   export default defineNuxtRouteMiddleware((to, from) => {
     const { user } = useAuth();
     if (!user.value) {
       return navigateTo('/login');
     }
   });

Then apply this middleware to your dashboard or protected routes. Remember, the 404 "User not found" error is coming from your API, not Nuxt itself. So, it's crucial to ensure that your backend authentication logic is working correctly and that you're sending the proper authentication credentials with each request. If you continue to face issues after trying these solutions, you may need to investigate your server-side code and authentication mechanisms more deeply. Nuxt Authentication (https://nuxt.com/docs/getting-started/authentication) documentation might provide additional insights into setting up authentication in your Nuxt 3 application. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai the error happens on the server side not on the network logs or console of dev tools

kapa.ai•15h ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Thank you for providing that additional information. It's important to understand that the error is occurring on the server side rather than in the browser. This changes our approach to troubleshooting. Let's focus on server-side issues in Nuxt. Based on the knowledge sources available, here are some potential reasons and solutions for your server-side error: 1. Server-side rendering (SSR) issues: The error might be occurring during the server-side rendering process. Nuxt performs initial data fetching on the server, which could be causing this issue. 2. Middleware execution: If you have any server-side middleware, it might be interfering with the request or not properly handling authentication. 3. API route implementation: The problem could be in how your API route for /api/auth/user is implemented on the server. Here are some steps you can take to address this: 1. Use setResponseStatus to handle the error: In your API route or server middleware, you can use setResponseStatus to properly set the error status. This will help Nuxt handle the error correctly during SSR.

   import { setResponseStatus } from 'h3'

   export default defineEventHandler((event) => {
     // Your authentication logic here
     if (userNotFound) {
       setResponseStatus(event, 404, 'User Not Found')
       return { error: 'User not found' }
     }
     // Rest of your handler
   })

   import { setResponseStatus } from 'h3'

   export default defineEventHandler((event) => {
     // Your authentication logic here
     if (userNotFound) {
       setResponseStatus(event, 404, 'User Not Found')
       return { error: 'User not found' }
     }
     // Rest of your handler
   })

This approach is documented in the H3 Utils documentation (https://h3.unjs.io/utils/response#setresponsestatusevent-code-text). 2. Implement error handling in your API route: Make sure your API route is properly handling cases where the user might not be authenticated or found. 3. Use createError for better error handling: Nuxt provides a createError utility that can be used to create errors with additional metadata. This can be helpful for debugging and handling errors consistently across your application.

   import { createError } from 'h3'

   export default defineEventHandler((event) => {
     // Your authentication logic here
     if (userNotFound) {
       throw createError({
         statusCode: 404,
         statusMessage: 'User Not Found',
         data: { /* additional error data */ }
       })
     }
     // Rest of your handler
   })

   import { createError } from 'h3'

   export default defineEventHandler((event) => {
     // Your authentication logic here
     if (userNotFound) {
       throw createError({
         statusCode: 404,
         statusMessage: 'User Not Found',
         data: { /* additional error data */ }
       })
     }
     // Rest of your handler
   })

This approach is documented in the Nuxt Error Handling documentation (https://nuxt.com/docs/api/utils/create-error). 4. Check your server middleware: If you have any server middleware, ensure it's not interfering with the authentication process. You might need to add some logging or debugging to your middleware to see if it's being executed as expected. 5. Verify server-side environment: Make sure your server has access to all necessary environment variables or configuration needed for authentication. 6. Use Nuxt's built-in error handling: Nuxt provides a way to handle errors globally. You can create an error.vue file in your project root to handle all errors, including 404s:

   <template>
     <div>
       <h1>{{ error.statusCode }}</h1>
       <p>{{ error.message }}</p>
     </div>
   </template>

   <script setup>
   const props = defineProps({
     error: Object
   })
   </script>

   <template>
     <div>
       <h1>{{ error.statusCode }}</h1>
       <p>{{ error.message }}</p>
     </div>
   </template>

   <script setup>
   const props = defineProps({
     error: Object
   })
   </script>

This is described in the Nuxt Error Handling documentation (https://nuxt.com/docs/getting-started/error-handling). Remember, server-side errors in Nuxt can be tricky to debug. You might need to add more logging on the server side to get a clearer picture of what's happening during the request lifecycle. If you continue to face issues, you may need to provide more details about your server setup and any custom server-side code you're using. Stack Overflow: Nuxt.js localhost redirects to /login automatically, resulting in 404 error (https://stackoverflow.com/questions/78746436) suggests that in some cases, this behavior might be caused by default settings in modules like Supabase. If you're using any authentication modules, make sure to check their configuration as well. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

I do not understand what is the cause of this weird behavior when I only called this api once but for some reason I first get empty values then later the logs have values? On the backend I get this error First the value is null then it returns a value

export default defineEventHandler(async (event) => {
    const cookies = parseCookies(event);
    const { user } = await validateSessionToken(cookies.session);

    console.log("USER: ", user);
    console.log("SESSION: ", cookies);

    if (!user) {
        throw createError({
            status: HTTP_STATUS.NOT_FOUND,
            statusMessage: USER_NOT_FOUND,
        });
    }

    const {
        password,
        id,
        createdAt,
        updatedAt,
        isVerified,
        ...userWithoutSensitiveInfo
    } = user;

    return {
        status: HTTP_STATUS.OK,
        body: { user: userWithoutSensitiveInfo },
    };
});

export default defineEventHandler(async (event) => {
    const cookies = parseCookies(event);
    const { user } = await validateSessionToken(cookies.session);

    console.log("USER: ", user);
    console.log("SESSION: ", cookies);

    if (!user) {
        throw createError({
            status: HTTP_STATUS.NOT_FOUND,
            statusMessage: USER_NOT_FOUND,
        });
    }

    const {
        password,
        id,
        createdAt,
        updatedAt,
        isVerified,
        ...userWithoutSensitiveInfo
    } = user;

    return {
        status: HTTP_STATUS.OK,
        body: { user: userWithoutSensitiveInfo },
    };
});

@kapa.ai whats the cause this issue ?

kapa.ai•15h ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the information provided in our conversation history and the available knowledge sources, there are several potential causes for the server-side 404 "User not found" error you're experiencing. However, without more specific details about your server-side implementation, it's challenging to pinpoint the exact cause. Here are the most likely reasons: 1. Authentication Issues: The error suggests that the server is unable to find or authenticate the user. This could be due to: - Expired or invalid session tokens - Incorrect handling of authentication headers on the server - Issues with server-side session management 2. API Route Implementation: There might be a problem with how the /api/auth/user route is implemented on your server. The route might be failing to correctly identify or retrieve the user based on the provided authentication information. 3. Middleware Interference: If you have server-side middleware in place, it could be interfering with the authentication process or not properly passing authentication information to your API routes. 4. SSR (Server-Side Rendering) Complications: The error occurs during server-side rendering, which suggests that the initial data fetching on the server is failing. This could be due to differences in how authentication is handled during SSR compared to client-side rendering. 5. Environment Configuration: There might be missing or incorrect environment variables on the server that are necessary for authentication. 6. Module Configuration: As mentioned in the Stack Overflow post about Nuxt redirects (https://stackoverflow.com/questions/78746436), some authentication modules (like Supabase) have default behaviors that can cause unexpected redirects or 404 errors. If you're using any authentication modules, their configuration might be contributing to this issue. To determine the exact cause, you would need to add more detailed logging on the server-side, particularly in your authentication logic and API route handlers. This would help trace the exact point where the user authentication is failing. Remember, this error is coming from your server-side code, not from Nuxt itself. To resolve it, you'll need to focus on debugging your server-side authentication implementation and API routes. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

$fetch request don't take context of your request on server side Use useRequestFetch()('/api')

Patrik•15h ago

https://nuxt.com/docs/api/composables/use-request-fetch

Nuxt

useRequestFetch · Nuxt Composables

Forward the request context and headers for server-side fetch requests with the useRequestFetch composable.

Patrik•15h ago

And you have 2 requests for same endpoint? First on server and second on client?

o.mOP•15h ago

I only have one request for 1 endpoint There are so many api call function use cases its making me crazy

Patrik•15h ago

But how you get 2 outputs in console?, Xd

o.mOP•15h ago

I dont know. I only called it once here

Patrik•14h ago

Looks like 1 request made on server and second on client Show me the code again

o.mOP•14h ago

so basically I only ran this one once

Patrik•14h ago

You better to use it inside a plugin Like getting user https://discord.com/channels/473401852243869706/1318526910703075399/1318532786914590751 Second link It's a bit complex but you need to get the idea

o.mOP•14h ago

I'm trying to get the idea Do I have to do it like this ? export default defineNuxtPlugin(async (nuxtApp) => { my useAuth() is basically jsut a composable

Patrik•14h ago

Inside a plugins folder Yes Yes You leave your composable as it is Then create a plugin

Patrik•14h ago

https://nuxt.com/docs/guide/directory-structure/plugins

Patrik•14h ago

And use your composable here To get the user From server And use user object here

o.mOP•14h ago

Whats the purpose of plugin?

Patrik•14h ago

But without get current user

o.mOP•14h ago

to initialize the user?

Patrik•14h ago

I've send you the docs Yes

o.mOP•14h ago

Not sure if this is the right approach but here is what I did

export default defineNuxtPlugin(async (nuxtApp) => {
    const { user, getCurrentUser } = useAuth();

    if (!user.value) {
        await getCurrentUser();
    }
});

export default defineNuxtPlugin(async (nuxtApp) => {
    const { user, getCurrentUser } = useAuth();

    if (!user.value) {
        await getCurrentUser();
    }
});

o.mOP•14h ago

I get hydration error after the implementation

o.mOP•14h ago

The const requestFetch = useRequestFetch(); really solved the backend errors Thanks a lot You are life savior. Thank you very much for your guidance!

Patrik•14h ago

Don't need to check it just call the method You can also call that composable inside a dashboard header component It's still there?

o.mOP•13h ago

the hydration error is fixed This seems to fix the issue const requestFetch = useRequestFetch();

Patrik•13h ago

yea

o.mOP•13h ago

Plugin runs in the client side ?

Patrik•13h ago

both

Why is it when I refresh the page I get api calls error?
