I've followed the Oustystems Integrating with OAuth Exercise but when I run my test application, I keep on receiving this error 400 Bad Request (Unsupported grant type/Invalid grant type). I also found this link https://www.outsystems.com/forums/discussion/43710/error-unsupported-grant-type-and-invalid-grant-type/ and able to apply some of the suggestions here but I'd still received the same error. 

Any suggestions?
