Sanity Navigation Error: TypeError: can't access property

Hi! I'm using Sanity in my project but I'm facing an issue with navigation. When selecting a project I initially get an error: Uncaught (in promise) TypeError: can't access property 0, $setup.project is null. However clicking the project again successfully navigates to it On the project page I am completely stuck and can't navigate the same error appears in console and I need to do a hard refresh to proceed. I'm using a simple groq query. Also there is a Could not access sanity warning. I'm just using the default config Does anyone know what might be causing this? Thanks in advance!

Hi @Xulo. 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 the knowledge sources, I can offer some insights into your Sanity navigation error, though I don't have a complete solution. Let's break down the issues: 1. Initial Error: The error Uncaught (in promise) TypeError: can't access property 0, $setup.project is null suggests that the project data is not immediately available when you're trying to access it. This could be related to the asynchronous nature of data fetching. 2. Navigation Issues: The fact that you're experiencing navigation problems and need to do a hard refresh suggests there might be an issue with how the router is handling the navigation or how the data is being loaded. 3. Sanity Warning: The "Could not access sanity" warning might indicate a configuration issue with your Sanity setup. Here are some potential causes and solutions to consider: 1. Asynchronous Data Loading: Ensure that you're properly handling asynchronous data loading. You might need to use await or handle promises correctly when fetching data from Sanity. This could explain why clicking a second time works - the data might have loaded by then. 2. Router Issues: There might be a problem with how your router is handling navigation between pages. This could be related to the Nuxt version you're using. Some users have reported similar issues with navigation in Nuxt 3.7.1. Stack Overflow - Nuxt3 app crashes when navigating (https://stackoverflow.com/questions/77081487) 3. Template Refs: If you're using template refs with v-for, especially on custom components, make sure you're accessing them correctly. There have been issues reported with this in Vue 3/Nuxt 3. Stack Overflow - Unable to access element with template refs (https://stackoverflow.com/questions/76859379) 4. Sanity Configuration: Double-check your Sanity configuration in your nuxt.config.ts file. Make sure you've correctly set up the projectId and other necessary parameters. Here's an example of a basic Sanity configuration:

   export default defineNuxtConfig({
     image: {
       sanity: {
         projectId: 'yourprojectid',
         // Defaults to 'production'
         // dataset: 'development'
       }
     }
   })

   export default defineNuxtConfig({
     image: {
       sanity: {
         projectId: 'yourprojectid',
         // Defaults to 'production'
         // dataset: 'development'
       }
     }
   })

Nuxt Image Sanity Provider (https://image.nuxt.com/providers/sanity) 5. Error Handling: Implement proper error handling in your components and pages to catch and handle these errors gracefully. This can help prevent the app from getting stuck and requiring a hard refresh. Without seeing your specific code, it's difficult to pinpoint the exact cause of the issue. However, these are common areas where similar problems can occur. If the problem persists after checking these areas, you might want to create a minimal reproducible example and seek further assistance from the Nuxt or Sanity communities. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Does not work, using navigateTo(/projects/${project.name}) gives the same issue @kapa.ai This is my sanity config in nuxt config // nuxt.config.ts sanity: { projectId: process.env.NUXT_SANITY_PROJECT_ID, },

Let me check the knowledge base for you again. One moment! :books: ---------------------- Based on the configuration you've shared, it appears that you're using environment variables to set up your Sanity project ID in the Nuxt configuration. This is a good practice for security and flexibility. However, there are a few things to consider: 1. Environment Variables: Make sure that your NUXT_SANITY_PROJECT_ID environment variable is properly set. According to the Nuxt documentation on runtime config (https://nuxt.com/docs/guide/going-further/runtime-config#environment-variables), Nuxt CLI has built-in support for reading your .env file in development, build, and generate modes. However, when you run your built server, your .env file will not be read automatically. 2. Configuration Structure: The configuration you've shown is slightly different from the example in the Nuxt Image Sanity Provider documentation (https://image.nuxt.com/providers/sanity). The standard structure is nested under the image key. Here's how it should look:

   export default defineNuxtConfig({
     image: {
       sanity: {
         projectId: process.env.NUXT_SANITY_PROJECT_ID,
       }
     }
   })

   export default defineNuxtConfig({
     image: {
       sanity: {
         projectId: process.env.NUXT_SANITY_PROJECT_ID,
       }
     }
   })

3. Runtime Config: If you need to access this value at runtime, you might want to consider using runtimeConfig. Here's an example of how you could set it up:

   export default defineNuxtConfig({
     runtimeConfig: {
       public: {
         sanity: {
           projectId: process.env.NUXT_SANITY_PROJECT_ID
         }
       }
     }
   })

   export default defineNuxtConfig({
     runtimeConfig: {
       public: {
         sanity: {
           projectId: process.env.NUXT_SANITY_PROJECT_ID
         }
       }
     }
   })

This way, you can access the Sanity project ID in your application using useRuntimeConfig(). 4. Environment Variable Naming: Ensure that your environment variable is correctly named. Nuxt uses a special naming convention for environment variables that override runtime config properties. They should be uppercase and start with NUXT_. Your current naming (NUXT_SANITY_PROJECT_ID) follows this convention correctly. If you've set up your configuration as shown above and are still experiencing issues, it might be worth double-checking that your environment variables are correctly set and that Sanity is properly installed and initialized in your project. If problems persist, you may need to provide more details about your setup or create a minimal reproduction of the issue for further debugging. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Found it: I used the wrong syntax: groq[_type == "project" && slug.current == "${slug}"]{ ... Instead of:const query = groq`[_type == "project" && slug.current == $slug][0]{ _id, title, description };

const { data: project } = await useSanityQuery<Project>(query, {
  slug: route.params.name,
});

Now it works!
