Troubleshooting

Common issues and solutions for the DMTR Chrome extension.

Common issues

Side panel shows "No entity detected"

  • Verify you're on a supported site (PitchBook company or investor profile page)
  • Check that the content script is injected: open DevTools on the page → Console → look for DMTR-related messages
  • The PitchBook DOM structure may have changed — check if h1 elements exist on the page

Side panel shows an error

  • Verify the DMTR API is running at http://localhost:3100
  • Test the API directly: curl http://localhost:3100/health
  • Check the service worker console: chrome://extensions/ → DMTR extension → "Inspect views: service worker"

Extension icon doesn't appear

  • Ensure the extension is loaded and enabled in chrome://extensions/
  • Pin the extension from Chrome's extension menu (puzzle piece icon)

Entity not resolving

  • The entity may not be in the seed data. The development seed includes ~20 companies.
  • Check the API directly: curl -X POST http://localhost:3100/v1/intelligence/resolve -H "Content-Type: application/json" -d '{"name": "Company Name"}'
  • The fuzzy matching threshold is 0.75 — very different names won't match

After rebuilding, extension doesn't update

  • Click the reload button on the extension card in chrome://extensions/
  • Close and reopen the side panel
  • If content scripts don't update, refresh the PitchBook page
