[midPoint] User activation of self registering process is not working in Midpoint 4.1 (docker official image)

[Luiz Gustavo Sathler Dias]

User activation of self registering process is not working in Midpoint 4.1
(docker official image), also tried 4.2.

Registering itself is working. The problem happens when the user receives
email and clicks on the link for activation.

That's the log I get every time a user tries to activate himself. Users
also stay in draft state without moving to enable state.
