The /build endpoint accepts optional values for start_component_id and stop_component_id to control where the flow run starts and stops. Setting stop_component_id for a component triggers the same behavior as clicking the Play button on that component, where all dependent components leading up to that component are also run. For example, to stop flow execution at the Open AI model component, run the following command:
