Hi everyone.
I have a weird problem while using Authorization Code Flow when I'm trying
to get a token with Postman and/or my web app (Angular).
In both cases I get to see a Keycloak login page and after I provide valid
credentials, Keycloak presents me an error:
"Unexpected error when handling authentication request to identity
provider.",
and an exception is thrown (logs):
"13:19:52,345 ERROR [org.keycloak.keys.FailsafeAesKeyProvider] (default
task-36) No active keys found, using failsafe provider, please login to
admin console to add keys. Clustering is not supported.
13:19:52,348 WARN [org.keycloak.services] (default task-36)

The mentioned error does not happen when i use a Direct Access Grant (using
the same user and his credentials)
and I'm able to get a proper access token. Definitely there is no problem
with LDAP connection.
Is this a configuration error and is there a workaround? If it's a key
problem or LDAP connection why does it pop up only with Authorication Code
Flow?
I tested it on versions 3.4.3 and 4.0.0.Beta1 and it happens on both of
them.
Best regards,
