Paste the error, find the root cause

I hit an error. Help me find the cause.

Full error (do not truncate):
```
{{paste the complete console or terminal output}}
```

Relevant code:
```
{{the code the error points at, plus its caller}}
```

Already tried: {{what you attempted}}
Environment: {{OS / language version / framework version}}

Answer like this:
1. In one sentence, what is this error actually saying (in plain words)?
2. The 2-3 most likely causes, ordered by probability, with your reasoning.
3. For each cause, the concrete fix.
4. How I verify it is actually fixed.

Rules:
- Do not rewrite the whole file upfront. Make the smallest change that locates the problem.
- If you lack information, say exactly which code or log you need. Do not guess.

Replace the {{}} parts with your own content

Why it works

1. "Translate it first" proves AI understood the error instead of keyword-matching
2. Ranked causes with reasoning prevent AI from confidently giving its most familiar but wrong answer
3. "Smallest change first" stops AI from rewriting broadly and burying the real cause
4. Letting AI say "not enough info" is far more efficient than forcing a guess

What it looks like

Paste a Hydration failed error plus the component, and AI identifies server/client output mismatch (e.g. Date.now()) and offers the useEffect or suppressHydrationWarning fixes.

Where it bites

• !Pasting only the last line - the stack above it is what actually locates the problem
• !Not listing what you already tried, so AI re-suggests the things that failed
