Exception Caught in dispatchtasksequence

At the beginning, the error was "offset travel tasks that don't have a valid destination set". After referencing this answer (https://answers.flexsim.com/questions/110072/agv-offset-travel-issue.html), I adjust the distance between cps, but it then pop out another error..
I have no idea why..
I would be appreciate if you have any idea to solve this error :)

Hi @Emily K,

This can be fixed by going to the properties of the Task Executer and select "Do not travel offsets and block space on network" instead of "Use navigator for offset travel." You will also need to adjust the control points so the one for IN is before the one for OUT. 1688423684150.png

Or, you can just have the IN and OUT queues connected to the same control point.

Unfortunately, I don't have good information on why this error is happening, but these steps should fix the problem for you.

You should refresh the path links of the entire network to ensure destinations are reachable - look to diamonds without a cross - these need fixing.


The offset travel will work in the currenlty supported versions of FlexSim.
