500Internal Server Error
PanicornStack TraceIt's not you, it's me.What it means
Something unexpected broke on the server.
Where you meet it
An unhandled exception in backend code.
What to test
- In DevTools (Elements tab), remove maxlength, required or pattern from the field and submit the form with unexpected data: emoji, a string one character over the backend or database limit, <script>, ' OR 1=1 → no 500: either a normal result or a validation error.
- If the form validates with JavaScript, copy the request in Network (Copy as fetch) or open it in Postman, put in the same data and send it → again no 500.
- If a 500 does happen, look at the page → a message for the user with no technical information (e.g., "Something went wrong, please try again").
- After a 500, check the logs or monitoring → the error is there with the time, URL and request details.
