group-sync-operator 0.0.27 crashes since upgrading to Keycloak 23 about group-sync-operator

[sabre1041]

@bo0ts The looks to be a communication issue from the operator and Keycloak and less of a compatibility issue

[bo0ts]

@sabre1041 I'm confused why you would think that. Everything was working fine until we updated the keycloak instance to version 23 and since then all our instances of group-sync-operator started crashing. All other Keycloak operations are also still working.

@bo0ts if you notice the error, it mentions EOF which typically refers to a connectivity issue to the endpoint

I have the same problem, Keycloak 23.0.1, group-sync-operator 0.0.27. I do not see any EOF in the log above or in our installation. The line:
1.7018618479017475e+09 INFO syncer_keycloak Successfully Authenticated with Keycloak Provider
indicates that the connection seems to work.
Does group-sync-operator expect something from Keycloak that now is missing?

@tormig-softronic @bo0ts The issue has been identified and will be submitting a patch to resolve shortly

[bo0ts]

@sabre1041 Could you be more open about what the issue was? I'm sure others can benefit from that knowledge as well.

[sabre1041]

@bo0ts the issue was a null check that needed to be added.

#299

However, if you look at the linked issue within the PR regarding an upstream bug, it may also be a side effect of that as well. But, the issue you are facing should be resolved with this enhancement

[bo0ts]

@sabre1041 Thanks, could you also publish a new release with that fix at is a real blocker to Keycloak upgrades?

[bo0ts]

@sabre1041 Ping about the new release?

[sabre1041]

@bo0ts we are resolving an issue with our release pipeline. expect a release this week
