413
4xx Client ErrorPayload Too Large
The request body is larger than the server is willing to process.
413 Payload Too Large (once called Request Entity Too Large) means the body exceeds a server limit - common when uploading files. The cap is often set by the web server or a proxy in front of your app, not the app itself, so check there first.
About 4xx Client Error
The request has a problem the client needs to fix, like a bad URL, missing auth, or invalid input.
How to fix 413 Payload Too Large
- Raise the upload limit (e.g. client_max_body_size in nginx).
- Check limits on any proxy, load balancer, or CDN in front of the app.
- For large files, use chunked or multipart uploads.
