Prompt
I'm getting this error: [PASTE ERROR AND STACK TRACE OR ATTACH SCREENSHOT]. What I was doing when it happened: [STEPS]. Expected: [EXPECTED]. Actual: [ACTUAL]. Find the root cause before proposing a fix. Walk through the stack trace, name the most likely cause and two alternatives, and say what evidence would confirm each. Then give the smallest fix, explain why it works, and add a test that would have caught it.
