Multipart Form File Upload Issues on Replit

File upload fails with 400 Bad Request or files aren't received. Multipart form handling has issues.

Multipart form configuration and size limits require proper setup.

Error Messages You Might See

Current request is not a multipart requestFile size exceeds maximum allowed size400 Bad Request

Common Causes

  1. File size exceeds max upload limit
  2. Form content-type not multipart/form-data
  3. @RequestParam name doesn't match form field
  4. Multipart request not enabled in config
  5. Memory limit exceeded for large files

How to Fix It

Set spring.servlet.multipart.max-file-size=10MB and max-request-size=10MB in application.yml. Use @RequestParam("fileField") MultipartFile file. Set @RequestMapping(consumes = MediaType.MULTIPART_FORM_DATA_VALUE). For large files, stream to disk instead of memory. Check client sends correct content-type header.
