i see this is the default task_defination template : https://github.com/PrefectHQ/prefect/blob/master/src/prefect/agent/ecs/task_definition.yaml But i am not sure if i need to pass anything or create a task definition template.

Hey @Abhishek, ECSRun will get merged with that. You don’t need to pass anything. Just saw Anna responded above. Will read that.
