Dustin,

I have to agree with the last response. As long as you are calling post_event as opposed to process_event, your reaction looks fine.  The issue might not be with this particular reaction. But if somewhere else you are inadvertently calling process_event while responding to a transition, you might be corrupting your state which is only later detected by this assertion.

but given that the error message says "Container" is the InitialState, I have to assume so.  Given that, I don't see how either Container or GripperPosition are inactive and don't know how to interpret this error.    I'd appreciate some guidance.



Your react function looks fine. Do you by any chance directly or indirectly call state_machine::process_event from inside the state-machine (e.g. in- state reaction, transition, entry action, exit action, etc.)?



Thanks,



Andreas
