No Source Code found for Nuxt Dev Tools.
I have migrated to Nuxt 4 and am using the nuxt seo tool to check the links but I get this message on the Dev Tool "No Source Code found"
I have added the srcDir path as the new app dir in the Nuxt Config but I am still getting this message.
srcDir: "app/",

----------------------
The message "No Source Code found" in Nuxt DevTools after migrating to Nuxt 4 is likely related to the new directory structure introduced in Nuxt 4. In Nuxt 4, the default source directory is now app/, and most of your application code (including pages, components, etc.) should be inside this app/ directory. Setting
Ensure your project structure matches the expected Nuxt 4 layout, with all your main folders (assets, components, pages, etc.) inside the app/ directory, and nuxt.config.ts at the project root (not inside app/): 2. DevTools Version:
Make sure you are using a compatible version of Nuxt DevTools (v2+ for Nuxt 4). You can install or update it with: And enable it in your nuxt.config: Or via the CLI: Nuxt DevTools Getting Started 3. Restart the Dev Server:
After making changes to your directory structure or config, restart your Nuxt dev server to ensure changes are picked up. 4. Check for Global/Old DevTools Installs:
If you previously installed @nuxt/devtools globally, it may cause conflicts. Uninstall any global versions: And check for any lingering references in your user directory (such as a .nuxtrc file) and remove them if necessary [GitHub Issue Reference]. 5. Nuxt SEO Tool:
If the SEO tool is expecting the old directory structure, ensure it is updated for Nuxt 4 compatibility. If you have confirmed all the above and the issue persists, it may be a bug or a compatibility issue with the DevTools or a related module. In that case, consider opening an issue on the Nuxt DevTools GitHub with details about your setup and directory structure. Summary:
- Use the new app/ directory for your source code. - Set
srcDir: "app/"
in your nuxt.config is correct for this structure Nuxt 4 srcDir docs.
However, if you are still seeing "No Source Code found" in DevTools, here are a few things to check:
1. Directory Structure:Ensure your project structure matches the expected Nuxt 4 layout, with all your main folders (assets, components, pages, etc.) inside the app/ directory, and nuxt.config.ts at the project root (not inside app/): 2. DevTools Version:

- Ensure DevTools is installed locally and enabled.
- Remove any global or old DevTools installations.
- Restart your dev server after changes.
If you follow these steps and still see "No Source Code found," the knowledge sources do not provide a more specific solution, and you may need to seek further support from the Nuxt community or GitHub issues.
