[keycloak-user] Keycloak adapter with policies returns bad request

[Pedro Igor]

Do you get anything in server logs ? It may be related with invalid client credentials.

I'm creating a POC application using playframework and angular. The
frontend will be protected using the keycloak javascript adapter and the
backend rest services will be a bearer-only application.

Without the policies turned on in the keycloak.json everything goes well.
But when I turn the policies by adding "policy-enforcer": { } on for the
rest services, I get an 400 Bad Request response from the Keycloak server
during initialization.
After some debugging I noticed it had to do with the initialization of the
PolicyEnforcer which attempts to call the following server keycloak
endpoint:
http://127.0.0.1:8080/auth/realms/local.development/protocol/openid-connect/token

Below you will find the stacktrace and request and response objects.
Hope someone can point me in the right direction. For instance how to
configure keycloak logging to get some more details on what the reason for
the 400 bad request is.
Many many thanks!
