Hi, I am using a custom authentication handler which checks a user against a one stored in elasticsearch. I have already created different authentication handlers and they all worked. But when using this one I am getting following exception:
2017-09-12 11:52:20,176 WARN [org.apereo.cas.web.flow.resolver.impl.InitialAuthenticationAttemptWebflowEventResolver] - <'principal' cannot be null.
