Debug a code error with AI

Paste the error message and your code, and AI gives you the most likely causes ranked plus the exact steps to fix it, without guessing.

A red error on the screen can eat your whole afternoon. This prompt doesn't guess: it ranks the causes by likelihood and gives you steps to check each one, like a senior would. Paste the error, the code, and get unstuck.

Full prompt
Act as a senior developer helping me debug, with method and no wild guessing.

I have an error I can't get past. Help me find the cause and fix it.

- The error (full message, exactly as it appears): [PASTE THE ERROR]
- The related code: [PASTE THE CODE]
- What I expected to happen: [WHAT IT SHOULD DO]
- What actually happened: [WHAT IT DOES]
- What I've already tried: [IF YOU TRIED SOMETHING]

Help me like this:
1. In one sentence: what that error is saying in plain words.
2. The most likely causes, RANKED from most to least likely, and why.
3. For the most likely cause: the exact steps to verify and fix it.
4. How to confirm it's resolved.
5. A tip so this kind of error doesn't happen to me again.

Rules: don't rewrite my code into something totally different without explaining why. If you're missing info to be sure, tell me exactly what you need to see (a file, a version, a log). Don't invent functions or libraries that don't exist.
