Well in my case, it’s a pod task

@task(task_config=Pod(...))
def test() -> str:
    return ""

I just ran

@task(
    task_config=Pod(
        pod_spec=V1PodSpec(
            containers=[
                V1Container(
                    name="primary",
                    resources=V1ResourceRequirements(
                        requests={"cpu": ".5", "memory": "500Mi"},
                        limits={"cpu": ".5", "memory": "500Mi"},
                    ),
                )
            ],
        ),
    )
)
def my_empty_pod_task() -> str:
    return "hello world!"

@workflow
def empty_pod_workflow() -> str:
    s = my_empty_pod_task()
    return s

without any issue. If there is a problem with this, it is a very large problem. Also, can I ask what the

Pod

definition is? Perhaps there is something that results in mis-formatted inputs / output values.

It seems the error is in single task execution

@Leiqing do you know what version of flyteadmin you are running?
