[keycloak-user] Error while loading the application

[Pulkit Gupta]

Hi All,

We are using Keycloak SAML adapters to authenticate our applications with
Keyclaok.
The setup was working fine and the applications were able to authenticate
the users.

However since today we are getting the below error while loading the
application and this is resulting in a black page for the client.

Can you please check in case anyone has seen this issue before. Is this
related to java versions as I have not changed anything in the environments
recently.
