This is the endpoint I have:

@PostMapping(value = "/file-upload", consumes = MediaType.MULTIPART_FORM_DATA_VALUE)
public List<FileReference> handleFileUpload(
        @RequestPart(value = "file", name = "file") MultipartFile[] file, @ApiIgnore HttpSession session) {
    return service.handleFileUpload(
            Arrays.stream(file).map(MultipartFileWithUUID::new).collect(Collectors.toList()),
            session);
}

This is the generated endpoint in the swagger.json (swagger 2.0):

...
  "post": {
        "tags": [
          "damage-report-controller"
        ],
        "summary": "handleFileUpload",
        "operationId": "handleFileUploadUsingPOST",
        "consumes": [
          "multipart/form-data"
        ],
        "produces": [
          "application/json"
        ],
        "parameters": [
          {
            "name": "file",
            "in": "formData",
            "required": false,
            "type": "array",
            "items": {
              "type": "file"
            },
            "collectionFormat": "multi"
          }
        ],
...

And here is the generated function:

 public handleFileUploadUsingPOST(file?: Array<Blob> ...) {

let headers = this.defaultHeaders;

header settings etc...

        // to determine the Content-Type header
        const consumes: string[] = [
            'multipart/form-data'
        ];


        const canConsumeForm = this.canConsumeForm(consumes);

        let formParams: { append(param: string, value: any): any; };
        let useForm = false;

...
        if (useForm) {
            formParams = new FormData();
        } else {
            formParams = new HttpParams({encoder: this.encoder});
        }
...
}

The error I have is 415: Unsupported media type.

I don't know how it should be generated correctly, but I changed let useForm; to true and it works, so my guess that let useForm = canConsumeForm(consumes) because canConsumeForm returns a boolean.

What should I change so it gets generated correctly?
