Login with OAuth 2.0 - invalid_user_info_response

I am trying to setup Flowable with a Keycloak integration.

When going to the root url of Flowable, i am being redirected to Keycloak, I can log in but when I am redirected to Flowable, I am seeing the following error message in the browser:

[invalid_user_info_response] An error occurred while attempting to retrieve the UserInfo Resource: 403 Forbidden: [no body]

I am running the .war file in a Tomcat Docker container. I have added the needed dependencies and added this in flowable-default.properties:

spring.security.oauth2.resourceserver.jwt.issuer-uri=https://DOMAIN/auth/realms/REALM
spring.security.oauth2.client.registration.keycloak.client-id=flowable
spring.security.oauth2.client.registration.keycloak.client-secret=SECRET

flowable.idm.app.keycloak.authentication-password=PASSWORD_IN_MASTER_REALM
flowable.idm.app.keycloak.realm=REALM

What am I doing wrong in my configuration?

Hi! Were you able to figure this out? Which Keycloak version are you using?
I’m experiencing the same issue with Keycloak 22.
