I see a few other requests about this, but so far not enough detail to get past my issue. This is Keycloak as used by Microcks, installed into OpenShift via the Microcks Operator.
I’ve tried to configure an Open ID provider, but after being redirected to my GHE login and approving it, Microcks gives the error screen/message:
We are sorry… Unexpected error when authenticating with identity provider
Looking at the log for the Keycloak pod, I see the following:
14:46:27,187 ERROR [org.keycloak.broker.oidc.AbstractOAuth2IdentityProvider] (default task-23) Failed to make identity provider oauth callback: org.keycloak.broker.provider.IdentityBrokerException: Could not decode access token response.

This looks like the key portion, which seems to indicate GHE is returning a different format response than Keycloak is expecting?

However, I don’t see anything in the Keycloak OIDC configuration to specify like the Accept header or anything.
