library generates a broken file

[delasource]

My swaggerfile accepts a parameter of type "multipart/form-data". I generate my client class like:

$ react-query-swagger /tanstack /input:http://localhost:5103/swagger/hubapi-v1/swagger.json /output:src/api/QueryClient.ts /template:fetch

The generated code contains the following method in QueryClient.ts (default output file):

uploadTaskAttachment(taskId: number, uploadTaskAttachmentRequest: Blob): Promise<UploadTaskAttachmentResponse> {
    let url_ = this.baseUrl + "/api/tasks/{taskId}/attachments/upload";
    ...

which is valid.

However, the generated "Query.ts" file contains an import of the Blob-type, which is invalid code, as "Types" does not contain the definition of Blob. Blob is a standard type that should not be ex nor imported.

import * as Types from '../QueryClient';

...

type UploadTaskAttachment__MutationParameters = UploadTaskAttachmentQueryParameters & {
  uploadTaskAttachmentRequest: Types.Blob;
}

This may be an issue in NSwag but i'm not sure. Maybe i have another problem in my swagger file. Any hints would be helpful, thanks.

It only happens with multipart/form-data. Other content-types result in (proper) application/json-requests.
