getting error in syslog after upgrade

[beingbaban]

We upgraded from otrs 5 to otrs 6, though the instance is working fine. on checking syslog, its generating following error.

Can someone suggest in this case what can be the issue.

Daemon Kernel::System::Daemon::DaemonModules::SchedulerGenericAgentTaskManager-10[928822]: [Error][Kernel::System::ObjectManager::_DieWithError][Line:536]: Kernel::System::Daemon::DaemonModules::SchedulerGenericAgentTaskManager depends on Kernel::System::DynamicField::Backend, but the constructor of Kernel::System::DynamicField::Backend returned undef

Check if you updated all packages and remove orphaned configuration with a rebuild (bin/otrs.Console.pl Maint::Config::Rebuild --cleanup).

Thank you for getting back. I checked, my otrs version is 6.0.40

while when I upgraded from otrs 5 to otrs6, following is the version of addon:

How I can go to 6.0.40 for addon? Can you please suggest.

The version of the package does not have to be equal to the product version. Did you rebuild the configuration? Open the dynamic field screen in the admin area and check if you get new error log entries.

OTRS 6 ends with version 6.0.30. The old Znuny 6 LTS ends with 6.0.48. You probably (intentionally or unintentionally) migrated to another fork.

In any case, you're using an outdated version and might consider upgrading to a supported one.

The errors that I posted are from /var/log/sysconfig.
I checked from frontend but dont see an option, can you suggest where I can see those logs. Its not in system log.

Also, from otrs 6.0.40, I should goto Znuny 6.1 or should try with 6.0.48?

You should at least go to Znuny 6.5 LTS.

You didn't provide any feedback on the rebuild cleanup outcome.
