ForbiddenError: Unable to load OAuth 2.0 transactions from session

When performing a POST request to my server.decision()/server.grant() endpoint using cUrl or POSTMAN client I get a good response and I receive the auth code I need for a POST request to my server.token()/server.exchage() endpoint.

However, when I generate a POST request using Angulars $http service, I recieve the following error.

I’ve done some searching through Google and the issues and I can’t seem to find anything that can help me.

Can anyone point me in the right direction?
