    One of my flows, which usually works just fine, failed yesterday with this unusual error:
    prefect.utilities.exceptions.ClientError: 400 Client Error: Bad Request for url: <https://api.prefect.io/graphql>
    
    The following error messages were provided by the GraphQL server:
    
        INTERNAL_SERVER_ERROR: Variable "$input" got invalid value null at
            "input.states[0].task_run_id"; Expected non-nullable type UUID! not to be null.
    
    The GraphQL query was:
    
        mutation($input: set_task_run_states_input!) {
                set_task_run_states(input: $input) {
                    states {
                        id
                        message
                        status
                }
            }
        }
    Runs (for different flows) after the failed run work again. This failed flow will run again at 4pm (in ~5h). Is this a known issue? Did I do something wrong?

    Hi @Sébastien it’s odd that this randomly occurred and everything after it worked fine 🤔 Do you happen to know the timestamp of when this was raised? Also I don’t think it’s anything you did wrong 🙂 seems like it could be a blip
