Dev server logs show:
[404] GET /todos/add-fields-to-page-meta/installHook.js.map

This is likely a browser extension (React DevTools, Vue DevTools, etc.) injecting installHook.js into the page and then requesting its source map relative to the current page URL. Need to confirm the source and decide whether to suppress or fix.

Things to Check

  • Does it reproduce with all browser extensions disabled?
  • Which extension injects installHook.js?
  • Does it happen on all todo pages or only this one?
  • Is it harmless noise or does it affect the build/SSG output?
