Hey, we are trying to set Camunda 8 self-managed up in a multi-namespace scenario (cf. Multi-namespace deployment | Camunda 8 Docs). We now have Identity and Console deployed in namespace-A and Zeebe, Elastic and Operate in namespace-B.
However, when we try to login to Operate, we are redirected to the Identity login and back. A session in Keycloak is created and in the Operate logs I can see that the operate/identity-callback is called. But we get an exception:

Not sure what happens there - can somebody point me to the right direction?
