What it means

A 414 URI Too Long response means the request URL exceeds the server's limit. This typically happens when too much data is passed in query string parameters instead of in the request body.

Common causes

• A GET request has too many or too long query parameters.
• Form data was submitted via GET instead of POST.

How to fix it

• Move large data from the URL to the request body using POST.
• Reduce the size of query parameters.
