Debugging Like a Pro

Console logs, network tab, and the built-in error reporter.

SYSTEM_PLAYBACK_ACTIVEVideo placeholder

When something breaks, the fastest path to a fix is evidence. Paste the exact error, share the failing network response, or take a screenshot of the broken UI. Lovable can read your console and network activity and usually finds the root cause in one shot.

/The debugging playbook

  • 01Read the red banner: Vite errors point at the exact file and line — paste that message in chat.
  • 02Open the console: Runtime errors, warnings, and your own console.logs live here.
  • 03Check the network tab: Look for red status codes and inspect the response body.
  • 04Reproduce it deliberately: If you can trigger the bug on demand, it's already half fixed.
  • 05Switch to Chat mode: Ask "why is this failing?" — Chat can inspect files without editing them.
Escape error loops

If the same fix has failed three times in a row, the diagnosis is wrong. Stop, describe what you've tried, and ask Lovable to propose a completely different approach.
