RelayFile Multipart FileUpload Issue

[rootandleaves]

I am tackling Relay Modern File Upload with Yoga-Server(Prisma Labs) which uses apollo-server behind the scene. Relay Only Upload Files as multipart to server for that i forked middleware which converts Relay Post request to multipart for uploadables(Uploading Files) Now when file recived on my server it is in Following format

Uploaded File

{
  height: Promise { <pending> },
  fileName: Promise { <pending> },
  fileSize: Promise { <pending> },
  width: Promise { <pending> },
  data: Promise { <pending> },
  type: Promise { <pending> },
  path: Promise { <pending> },
  timestamp: Promise { <pending> },
  originalRotation: Promise { <pending> },
  isVertical: Promise { <pending> },
  uri: Promise { <pending> },
  filename: Promise { <pending> }
}

1. If You Resolve all pending promises these are empty values where relay is sending these value but values are empty on server side don't know why.
2. I Consider UploadedFile to be in following format { filename, mimetype, createReadStream } but relay is not doing it instead of it i am reciving long object with all fields related to image and value of these keys are empty.

Please help to Configure my upload system properly. i am already trying for last 3 days...:*(
