The prompt
Given this stack trace <paste>, point to the exact line responsible and explain in 2 sentences what is null/undefined/throwing and why.

Why it works

Capping the answer at two sentences forces a precise diagnosis instead of a wall of speculation. It’s ideal for the first 30 seconds of triage before you decide how deep to go.

Fill in

  • <paste> — the stack trace (include the top frames from your code).

Follow-ups

  • “Now show the smallest change that prevents this.”
