SpringBoot why Bad Request, status=400 when i upload files?

Error Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback.

Tue Jan 25 13:54:17 YEKT 2022 There was an unexpected error (type=Bad Request, status=400).

Controller

@GetMapping("/uploadtest")
    public String uploadtest(Model model) {
         return "upload";
    }

    @PostMapping("/postupload")
    public String postupload(@RequestParam("files") MultipartFile[] images,Model model) {
         return "upload";
    }

form ```

Upload

``` when i remove @RequestParam("files") MultipartFile[] images the error disappears why error?
