Problem with document upload via Postman and Rest

Hello,

I am trying to upload a file via Postman and the postman collection provided by docuware (See attached screenshot).

However  when i submit the request with the attached document and index file there is no upload occuring.

It is simply returning the listing of all documents in the file cabinet as if i just make a get call to  OUR_DOCUWARE_URL/DocuWare/Platform/FileCabinets/111524bd-c059-4807-b380-cb15b62132be/Documents

What is missing here?
