Context

I'm testing the File Upload feature in Apollo sandbox

Everything looks good except that Apollo sandbox is sending the wrong mimetype application/octet-stream.

We are following the GraphQL multipart request spec

In our server we get the file but with the wrong mimetype

filePromise: Promise {
  {
    filename: 'pdf_file.pdf',
    mimetype: 'application/octet-stream',
    encoding: '7bit',
    createReadStream: [Function: createReadStream]
  }
}

filePromise: Promise {
  {
    filename: 'png_file.png',
    mimetype: 'application/octet-stream',
    encoding: '7bit',
    createReadStream: [Function: createReadStream]
  }
}

When we use Apollo client with any front end application we don't have this issue.

If we do the same request using Postman for example everything works perfect too.

So this is something that is happening only with Apollo sandbox we are missing some configuration in Apollo sandbox to send the right mimetype or this could be a bug?
