New crashing when workflow links to a state with scene

VeraPlus, version 1.7.2044, AltUI v1.60.1810

This is now occurring on several worflows/scenes that have been in place for a couple months and I cannot pinpoint it to any one change. As you can see from the log, a transition starts to occur, the state has a scene in it and crashes. This on seems to happen on time based/scheduled transitions. If I remove the scene from the target state, it stops the crash.

Any input is welcome.

what does the scene do ? is it lua code ? is it long ?

can you run ALTUI in debug mode and capture the complete luup log ?

also would like to get the workflow definition, you can get it from misc / deubg / javascript code
WorkflowManager.getWorkflow(“0-nn”) where nn is your workflow id
