I'm trying to use this module, but can’t seem to figure out how to get it to run a simple microflow. We are using Mendix Studio Pro 8.18.7 with scheduler version 1.5. I’ve added the after start up & before shut down microflow calls to our runtime. I’ve created a basically empty microflow that simply writes ‘Just a test’ to the log. I’m getting the below error when it tries to execute the action.   Exception in execution of monitored action 'Scheduler.SE_EvaluateOpenInstructions' (execution id: 07f8ce0d-3b17-4e1f-aef5-408035c4cfc2, execution type: SCHEDULED_EVENT) -------- com.mendix.modules.microflowengine.MicroflowException:

Any guidance appreciated.
