Petit test
Guess first, no penalty. Your app throws KeyError: 'user_id' in production. Which message to the AI gets the most useful answer?
A stack trace is the list of function calls that led to an error, printed with the error itself. It's the most useful thing you can paste, so paste all of it.
A good debugging request has five parts:
- The exact error and stack trace.
- The code involved: the function, and how it's called.
- Expected vs actual: what should happen, and what does.
- What you've tried, so it doesn't suggest the same thing.
- The ask: likely causes, ranked, and how to confirm each one. Not a patch yet.
Asking for causes before a patch matters. A patch for a cause nobody confirmed can hide the symptom and leave the bug in place. So confirm the root cause first, with a test that fails for exactly that reason. Then accept a fix only when that test passes.
