Could not resolve component "default"

Hi guys, I've got a big Nuxt App, and i randomly got an error Coule not resolve component "default" at /folder/:id(). I've this randomly in production, but not at all in dev. I have this since i migrated to 3.16. Is this a known issue ? It's hard to give you a reproduction as I have hundreds of files, but if you have ideas of what i can do to debug this ?

Hi @Quentin. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- This issue—"Could not resolve component 'default'" appearing randomly in production after upgrading to Nuxt 3.16—does not have a direct mention in the provided knowledge sources. However, several related issues have been reported after upgrading to Nuxt 3.16.x, especially around module resolution, build output, and compatibility with certain package managers (notably pnpm) and plugins. Here are some relevant findings and suggestions based on the knowledge sources: 1. Build/SSR Differences Between Dev and Production:
Multiple issues have been reported where the development environment works fine, but production builds (especially with pnpm and certain plugins) result in errors or missing exports. For example, errors like ReferenceError: shared_cjs_prodExports is not defined and issues with module resolution have been observed only in production or preview builds, not in development. This suggests that the build process or module resolution in production may be causing your issue as well Nuxt 3.16.0 build and run preview error 500 ReferenceError: shared_cjs_prodExports is not defined. 2. Potential Workaround for Build Issues:
One workaround for certain build-related issues is to adjust the Vite Rollup options in your nuxt.config.ts:

   export default defineNuxtConfig({
     vite: {
       $server: {
         build: {
           rollupOptions: {
             output: {
               preserveModules: false
             }
           }
         }
       }
     }
   })

   export default defineNuxtConfig({
     vite: {
       $server: {
         build: {
           rollupOptions: {
             output: {
               preserveModules: false
             }
           }
         }
       }
     }
   })

This workaround has resolved some production-only errors for other users after upgrading to Nuxt 3.16.x, particularly when using pnpm and certain UI libraries. It may help with your issue if it's related to module resolution during the build process Nuxt 3.16.0 build and run preview error 500 ReferenceError: shared_cjs_prodExports is not defined. 3. Component Name Normalization:
Nuxt 3.16 introduced changes to how component names are normalized for auto-imports. If you rely on dynamic or default layouts/components, ensure that your component names and usage match the new conventions. You can control this behavior with the experimental.normalizeComponentNames option in your nuxt.config.ts. If you suspect the issue is related to component name resolution, try toggling this option:

   export default defineNuxtConfig({
     experimental: {
       normalizeComponentNames: false // or true, depending on your needs
     }
   })

   export default defineNuxtConfig({
     experimental: {
       normalizeComponentNames: false // or true, depending on your needs
     }
   })

Normalized Component Names 4. Debugging Steps: - Try running a clean build: delete .nuxt, node_modules, and lock files, then reinstall dependencies. - If using pnpm, try switching to npm or yarn to see if the issue persists, as some issues are pnpm-specific. - Check for any custom plugins or modules that might be interfering with component resolution, especially if they manipulate layouts or dynamic imports. - Review your usage of <NuxtLayout>, <NuxtPage>, and dynamic components to ensure they align with the latest Nuxt conventions. Summary:
While the exact error message "Could not resolve component 'default'" is not explicitly documented in the knowledge sources, there are known issues with module resolution and component naming after upgrading to Nuxt 3.16.x, especially in production builds. Try the suggested workarounds and debugging steps above. If the issue persists, consider creating a minimal reproduction or sharing more details with the Nuxt community for targeted help. If you need more specific guidance, please provide additional context or a minimal reproduction if possible. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
