Exception thrown in state 'DisplayUsernamePasswordPage' of flow 'authn/Password'

[Marco Pirovano]

Hello,

we are running Shibboleth IdP 3.3.3.

We are getting a lot of this error in idp-warn.log:

2019-01-15 00:00:09,588 - ERROR [org.springframework.webflow.execution.FlowExecutionException:76] -

Do you have any suggestion ?

Thank you very much.
