Hi Railway team,

I’m encountering a 413 Payload Too Large error when uploading large files to my Railway backend only in production.

Details:

• Backend hosted on Railway
• Frontend works correctly from localhost → Railway backend with same files.
• When frontend is deployed and hits the same Railway backend, file upload returns 413
• Small requests work; only large file uploads fail
• Backend logs show the request does not reach the application when uploading large files.

This makes me suspect a proxy or request body size limit on the Railway edge or runtime.

Could you please confirm:

• Whether Railway enforces request/body size limits for incoming uploads
• If so, what the current limits are and whether they’re configurable

Thanks in advance.

Best regards,

Awa
