413 Content Too Large

The server refused to process the request because the request body is larger than the server is willing or able to handle.

Observed message

413 Content Too Large

Why it happens

  • The request body exceeds the configured upload or body-size limit.
  • A file upload, encoded payload, or batch request is too large for the endpoint.
  • A proxy or upstream server applies a lower size limit than the application expects.

How to fix it

  1. Reduce the size of the request body if possible.
  2. Use chunked or multipart upload workflows for large payloads.
  3. Increase body-size limits on the server or proxy only if that is safe for the application.
