Unexpected token ';' when refreshing every page

I don't know what's causing this and it's driving me insane. I keep getting an error "Unexpected token ';' and then the attached trace. I can't figure out why. Some refreshing of files may fix it sometimes or if I navigate back home then go back to where I was, that can fix it too. But why is this happening?

Hi @Tyr4el. 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, it appears that you're experiencing an issue related to Nuxt's error handling and possibly hydration errors. While there isn't a direct solution to your specific problem in the given sources, I can provide some insights and suggestions based on similar issues reported by other Nuxt users. The error "Unexpected token ';'" you're encountering could be related to a few different factors: 1. Hydration Errors: As mentioned in the Stack Overflow post about hydration errors (https://stackoverflow.com/questions/78477429), sometimes class mismatches can occur when refreshing pages. This might be causing unexpected behavior in your application. 2. Caching Issues: The Stack Overflow post about useFetch (https://stackoverflow.com/questions/77073604) suggests that sometimes Nuxt caches data and doesn't re-fetch when it thinks it's the same API call. This could potentially lead to unexpected tokens if the cached data is somehow corrupted or mismatched. 3. Build or Deployment Issues: As discussed in a Github issue about CSS preloads (https://github.com/nuxt/nuxt/issues/26972), sometimes errors can occur when a new app version is deployed and the client hasn't refreshed the page, leading to attempts to load resources from an old build. To troubleshoot this issue, you could try the following: 1. Add a unique key to your useFetch calls to prevent caching issues:

   const { data: res } = await useFetch(
     "your-api-endpoint",
     {
       key: Date.now(), // Add this line
       // other options...
     }
   );

   const { data: res } = await useFetch(
     "your-api-endpoint",
     {
       key: Date.now(), // Add this line
       // other options...
     }
   );

2. Check for any class mismatches in your components, especially those that use conditional classes. 3. Ensure that your build process is clean and that you're not mixing old and new build files. 4. Consider implementing error handling as described in the Nuxt Error Handling documentation (https://nuxt.com/docs/getting-started/error-handling). This might help you catch and diagnose the error more effectively. If the problem persists, you might want to create a minimal reproduction of the issue and seek further assistance from the Nuxt community or file an issue on the Nuxt GitHub repository. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Ah thank you 😄 I'm sort of confused on when to use useFetch and when to use $fetch. Do I use $fetch on client and server? For example, in my page and on my route

You are using useFetch WRONG! (I hope you don't)

💪🏻 useFetch is a mighty composable to fetch data in your Nuxt.js application. It can do so many things, from updating state to refreshing calls easily and even data caching is possible. But often I see that people misuse useFetch because it is so tempting to use all the features, even when you shouldn't. In this video I show the most common mist...
