Hi

We encounter that the Conditional Authenticator report successful authentication, but when it tries to clean up the Authenticator? keycloak sends a warning message that the fallback code is missing.
And the Authentication fails.

This code works in Keycloak 26.3 (if I recall?), so my question is if someone remember if this was a known issue?

Regards Tomas

Hi Tomas,

if you think this is a bug, please open a GitHub bug issue so we can triage it / investigate it. 

Best,

I resolved it by simply adding fallback Authenticator function in the Conditional Authenticator code and inherit Authentication into the Conditional Authenticator code.

Can send you the code if you want?
