The connector will need to format the request into a JSON body. Make sure you configure your HTTP Connector similar to the following:

"HTTP_action": {
   "inputs": {
      "body": {
         "$content-type": "multipart/form-data",
         "$multipart": [
            {
               "body": "@trigger()",
               "headers": {
                  "Content-Disposition": "form-data; name=file; filename=myExcelFile.xlsx"
               }
            }
         ]
      },
      "method": "POST",
      "uri": "https://finance.contoso.com"
   },
   "runAfter": {},
   "type": "Http"
}

where triggerbody() is the file content. Check for any difference between this and your Postman request.
