    Flow Engine

    PRB1880998

    		 Unable to deserialize Make a decision instruction after upgrading to Yokohama

    When the flow is in a 'Waiting' state in the Washington DC release with Engine_V2, the event opening the flow execution fails after upgrading to the Yokohama release.
    1. Create a flow with a Make a decision flow logic.
    2. Ensure the flow has a waiting scenario so that flow_context goes to a 'Waiting' state.
    3. Execute the flow.
    4. Ensure the flow is in a 'Waiting' state in the Washington DC release with Engine_V2.
    5. Upgrade the instance to Yokohama.
    6. Notice that the event opening the flow execution in Operation view fails, and resuming the flow by satisfying the waiting condition fails.

    Expected behavior: The flow should resume on Yokohama without any errors.

    Actual behavior: The flow errors out in Yokohama.
