Exception caught in Executive::processeventinlist() , AGV model

I am in the process of changing an AGV model from 3D model logic to List and Process Flow Logic.

There are two layouts in the attached model, the green plane is based on 3D logic and is working. The red plane is where I am seeing the error, specifically when the AGV arrives at a control point after leaving the bottom "Sink1".

Exception caught in Executive::processeventinlist().

I believe this error is related to the list, but I cannot pin-point nor resolve my issue. If I make an intermediate setup (Task Sequence list without Process Flow) I can reproduce the same error.

Software Version:

FlexSim 23.0.2

agv tasklist

Unrelated to the exception - just note that sampling the group, as you have, as the instanced/members doesn't result in the whole group being members. You should use the Group option under the Add members button. In this case the net effect happens to be the same as the group has one member and it gets added.

Hi @Phil Steinke,

You can fix this by changing the travel properties of the AGV from "Use navigator for offset travel" to "Do not travel offsets for load/unload tasks."

Oddly, you can also fix this by adjusting the locations of the control points.

Everything should be working as is, though, so we will be letting our development team know about your issue.
