Hell0!
Trying to build NetXMS for testing, currently everything works and is pulled but one thing - User Sessions tab, it gives an error "Cannot get list of active user sessionss: Operation cannot be completed due to agent error".
Server is built using a default docker file, agent is installed on 2 linux machines, one with static agent, another one was built from source.
The only error I found was in debug:
2026.02.27 11:33:32.780 *D* [comm.cs.1 ] Received message CMD_GET_TABLE (32)2026.02.27 11:33:32.780 *D* [comm.cs.1 ] Requesting table "System.ActiveUserSessions"

I wonder what can I look into to troubleshoot.
