Hi @DJ Erraballi - You'll need to add another task in here to handle your parameters. Something like this:

@task
def create_parameter_payload(result, param):
    return {'blah': param, 'resultId': result}

params = create_parameter_payload.map(param=unmapped(param), result=a_results)

flow_run_task.map(flow_name=unmapped('DownstreamFlow'), parameters=params)

You may need a (unmapped) project name in there too.
