Cannot save build via BuildManager - UnsupportedAgentOperationException #3747

Hello,

I'm struggling with this exception:

com.pmease.quickbuild.persistence.UnsupportedAgentOperationException: This operation is not supported at agent side.

Does it mean, that some classes/methods can be used/invoked only on QuickBuild server?

This script works as expected on the QB machine, but fails during runtime on any build agent.

groovy:
import com.pmease.quickbuild.BuildEngine
import com.pmease.quickbuild.BuildRequest
import com.pmease.quickbuild.*;
import com.pmease.quickbuild.model.*;
import com.pmease.quickbuild.entitymanager.*;

build.variableValues.put("NEW_VAR_1","")
build.variableValues.put("NEW_VAR_2","default")
system.buildManager.save(build)

Failing line of code:

system.buildManager.save(build)
