I can't upload from a file after uploading from a URL.

I can't upload from a file after uploading from a URL.
Maybe the content type of the request is still in json.
Is there a way to fix it?

Reproduction of the request

first request (from local file)
`Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryuHTzdLz0RSAlMUhc`

second request (from url)
`Content-Type: application/json`

third request (from local same file)
`content-type: application/json; charset=utf-8`

settings
```

additionalRequestHeaders:{
