I encountered a java.lang.NullPointerException while attempting to login to the SEB Server (version 1.5.2). The error trace suggests it originates from the PageServiceImpl and LoginPage classes. I'm stuck on how to resolve this issue. Has anyone faced a similar problem and found a solution?

Additionally, I'm relatively new to SEB Server and would appreciate guidance on resources or tutorials that provide comprehensive instructions on setting up and effectively using SEB Server 1.5.2. Any community-recommended guides or resources would be immensely helpful.

Thank you in advance for your assistance!
