I have regist this task succesfull, when i try to run this task. I have test locally and successful use sensor infinity. But when run on remote, the task sensor is aborted and take this error from Flyte console UI.

`Workflow[flytesnacks:development:<http://sensor_task.wf|sensor_task.wf>] failed. RuntimeExecutionError: max number of system retry attempts [11/10] exhausted. Last known status message: failed at Node[n0]. RuntimeExecutionError: failed during plugin execution, caused by: failed to execute handle for plugin [container]: [BadTaskSpecification] invalid TaskSpecification, unable to determine Pod configuration'

@Kevin Su, any idea what might be causing this error?

you need to enable the plugin in propeller, like

tasks:
  task-plugins:
    enabled-plugins:
      - agent-service
    default-for-task-types:
      - sensor: agent-service
