What it checks
Framework error screens in a page that otherwise returned 200 (Next.js, Remix, React).
Why it matters
Visitors see an error instead of your app, while monitoring that only checks the status code thinks everything is fine.
Recommended fix
Find the failing code path in the server logs and fix it; add an error boundary that shows a helpful message.
How to verify
Reload the page and confirm the error text is gone.
Example fix prompt
Generic prompt (your report adds the evidence)
Please fix this production issue in my app.
Issue REL-007: Page shows an application error message
Site: https://your-app.example
First confirm the issue in the code or live config. If it is not present, say so and change nothing.
Task: The homepage renders the framework error in the evidence while returning 200. Check the server and browser logs for the underlying exception, fix it, and add an error boundary with a friendly fallback.
Constraints: make the smallest change that fixes this, keep the current design and behaviour, never paste secret values into code or chat, and tell me which files you changed.
Done when: Reload the page and confirm the error text is gone.
