The error traceable logs looked like this. I’m not sure if this is relevant, however even though my credentials were valid, I don’t believe that they were rejected. It worked when I tried it with oauth/token as well. The error persists. I possess.

Solution:

The request that is dispatched is without the credentials added in the preceding line.

The reason being that Request::create returns a new request instance.

Add the request parameters in the newly created on $request and then dispatch it.
