Red Is Not Catastrophe

The first time Bolt or Lovable shows you a red error screen you will panic. That is normal. Errors are the app's way of telling you exactly what confused it. AI is incredibly good at reading these messages — if you paste the right parts.

The full error message — every line, including the scary call stack
The file name and line number it points at
What you did right before the error appeared
Whether it worked 10 minutes ago or never worked

My app crashed with this error: TypeError: Cannot read properties of null (reading 'id') at Dashboard (app/dashboard/page.tsx:23:18) at Object.renderWithHooks () This happened right after I added the filter tabs in the last prompt. Before that, the page loaded fine. What's going on, and what's the smallest change that fixes it?A great debugging prompt: exact error, exact location, what changed, and a request for the smallest fix.

Error	Usually means
Cannot read properties of the missing detail	Data wasn't there when the page tried to use it
Module not found	Missing install — ask AI to install the package
Hydration mismatch	Server and browser rendered different HTML
Unauthorized / 401	API key missing or wrong env variable name

Open a brand-new chat — context can get polluted
Try a different model — Opus, Sonnet, GPT-5, Gemini
Delete the offending feature and rebuild it from a cleaner prompt
Ask a human friend who codes — sometimes a fresh brain sees it in 30 seconds

The big idea: errors are letters from your app, not insults to you. Read them, paste them, ask for the smallest fix, and you will get unstuck ninety percent of the time.
