I get an error when running the MeetingAssistantFlow example “ValueError: Flow state model must have an ‘id’ field”. The LeadScoreFlow example works without any issues so I’m not sure what is wrong with the MeetingAssistantFlow. Any help would be appreciated.

Full details below:

Are you, by any chance, using the `@persist` decorator in your flow? If so, you need to pass in an ID in your inputs on `kickoff()`.

I do not see the @persist decorator. Here is the example from crewai - I would have expected this just work in its basic form as it would have been tested already. Any suggestions?
