Hi @mohamed! Could you tell us how did you fix error?
We got same error after upgrade on Keycloak 12.04 and Camunda 7.15 and using newer plugin version (GitHub - camunda-community-hub/camunda-bpm-identity-keycloak: Camunda Keycloak Identity Provider Plugin):
…
‘processEngineFactoryBean’: FactoryBean threw exception on object creation; nested exception is org.camunda.bpm.engine.impl.identity.IdentityProviderException: Unable to read data of configured administratorGroupName camunda-admin
…
With new plugin there is property: plugin.identity.keycloak.administratorGroupName=camunda-admin
If I remove property Camunda will start, but another error will occur later.
It is interesting if we use Keycloak with Docker error does not happen. But in production we have Keycloak without Docker. Both Keycloaks have same version and camunda-client settings are same.
There is also one more identical question on Camunda forum: Camunda and keaycloak users integration . It is also not answered.
