How to share file with room in HipChat via Postman or Jersey client?

Question

Please provide the solution for this (I am new to jersey and postman). I tried with below link but unable to share the file: https://www.hipchat.com/docs/apiv2/method/share_file_with_room

I attached screen shots, which I tried from postman.

Note: I used API access token with send message scope.

I am getting below error as response:

{
"error": {
"code": 400,
"message": "No file was found in the request. See https://www.hipchat.com/docs/apiv2/method/share_file_with_room for an example",
"type": "Bad Request"
}
}
