Error Explainer

Paste a confusing error message or stack trace and get a plain-English explanation, plus what to check first.

Error message or stack trace

Paste it raw, messy is fine. More of the trace usually means a more specific answer.

Language or frameworkOptional

Optional, but it sharpens the answer. e.g. "Python, Django", "Node, Next.js", "JavaScript in the browser".

What you were trying to doOptional

Optional. What you were doing right before this happened, helps narrow the diagnosis.
