Hmmm, that's odd. I'm trying it right now and it's working for me.

I was having the same problem with OAuth, but after hard-coding the Authorization header, I was able to get it working.

After working with Apigee support team, identified that our proxy internal server was stripping off Authoriziation header that produced above response. Bottom line, Apigee would return that error when no Authorization header was send in the request.
