Oauth accessing claim info

I have setup a authorisation server on a vcmp and a client resource server on another vcmp

I have a scope - Alex-Scope

and I have claims

alex1

alex2

...

I use opaque tokens so the client/resource vcmp send a oauth bearer token to the back end app.

Now I have having issues getting access to the claims with that token

making a call to 

/f5-oauth2/v1/userinfo

with the bearer token opaque says invalid user/password

calling 

/f5-oauth2/v1/introspect

doesn't give me claim info 

how do i get to claim info
