What it means

A 413 Payload Too Large response indicates the request entity is larger than the server can or will handle. This often happens with file uploads when the file exceeds the server's configured limit.

Common causes

• A file upload exceeded the server's maximum size.
• An API request body is too large.
• Server upload limits are too restrictive.

How to fix it

• Reduce the size of the upload or split it into smaller pieces.
• If you are the server admin, increase the upload size limit in your server config (such as client_max_body_size in nginx or upload_max_filesize in PHP).
