I am uploading a file from Microsoft Powerautomate to Springboot API. Getting exception "errorMsg": "Failed to parse multipart servlet request; nested exception is .apache.tomcat.util.http.fileupload.FileUploadException: Header section has more than 10240 bytes (maybe it is not properly terminated)"
API is working with Postman and Angular framework
API Details

@PostMapping(value = "/v1.0/import", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public ResponseEntity<Void> import(
               @RequestHeader(AirportConstant.AIRPORT_HEADER) String auth,
               @RequestParam("file") MultipartFile file,
               @RequestParam("userId") String userId,
               @RequestParam(value = "icao") String icao,
      @RequestParam(value = "entity", required = false) String entity) throws GlobalException {
        LOGGER.info("::  entering into  import ::");
