Hi @Quentin. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- When you encounter a white screen and an error like "error caught during app initialization $d" in a Nuxt app, it typically means a fatal error occurred during the app's startup phase. This can be caused by various issues, including chunk loading errors, misconfigured plugins, or problems in your code. Possible Causes and Debugging Steps 1. Chunk Loading Errors - Nuxt can encounter chunk loading errors if a JS chunk fails to load, often due to network issues or a new deployment invalidating old chunk URLs. By default, Nuxt will perform a hard reload when this happens, but you can customize this behavior with the experimental.emitRouteChunkError option in your config. If you want to handle these errors manually, you can refer to Nuxt's automatic implementation for ideas.
Error Handling Docs 2. Error Handling in Nuxt - You can set up global error handlers using the vue:error hook or vueApp.config.errorHandler in a Nuxt plugin. This allows you to log or handle errors globally:

     export default defineNuxtPlugin((nuxtApp) => {
       nuxtApp.vueApp.config.errorHandler = (error, instance, info) => {
         // handle error, e.g. report to a service
       }
       nuxtApp.hook('vue:error', (error, instance, info) => {
         // handle error, e.g. report to a service
       })
     })

     export default defineNuxtPlugin((nuxtApp) => {
       nuxtApp.vueApp.config.errorHandler = (error, instance, info) => {
         // handle error, e.g. report to a service
       }
       nuxtApp.hook('vue:error', (error, instance, info) => {
         // handle error, e.g. report to a service
       })
     })

Error Handling Docs 3. Error Page Customization - If a fatal error occurs, Nuxt will show a full-screen error page. You can customize this by adding an error.vue file in your source directory. You can also use the clearError helper to clear the error and optionally redirect the user. Error Page Docs 4. Third-Party Extensions - Sometimes, browser extensions (like ModHeader) can interfere with chunk loading and cause errors. Disabling such extensions has resolved similar issues for other users. Stack Overflow Example What to Do Next - Check your browser console for more detailed error messages. - Try disabling browser extensions to see if the issue persists. - Set up a global error handler as shown above to capture more information about the error. - If the error mentions chunk loading, consider the possibility of a deployment or caching issue. If you continue to see the error and can't trace it to a specific chunk or plugin, try to reproduce the issue in a minimal setup or after clearing your .nuxt and node_modules directories and reinstalling dependencies. If you need more targeted help, please provide the full error message and any relevant logs from your browser console or server output. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Do you have a component called default in your components folder? Maybe you put the wrong component name

QuentinOP•3mo ago

Not in components root, but one in /components/mail/template/Default.vue But i got this error randomly, and it could happen in pages that don't do nothing with that default component

WiFi Plug•3mo ago

Wouldn’t the component name be <MailTemplateDefault /> if you use folders?

QuentinOP•3mo ago

yes, but we have this in an enum file, which is called il nearly the whole app 😅 Maybe it can come from here ?
