Hello,
I’m trying to integrate Keycloak with a OpenID Connect identity provider (GitHub in my case)
I got the following error:
ERROR [org.keycloak.broker.oidc.AbstractOAuth2IdentityProvider] (executor-thread-153) Failed to make identity provider oauth callback: org.keycloak.broker.provider.IdentityBrokerException: Could not decode access token response.
Jun Caused by: com.fasterxml.jackson.core.JsonParseException: Unrecognized token ‘access_token’: was expecting (JSON String, Number, Array, Object or token ‘null’, ‘true’ or ‘false’)
Any idea about to reason of this error ?
How should I configure the Client Authentication (4 options) and Assertion Signature Algorithm (12 options) ?
