Hi team, I found that executing tasks with out no parameter renders an error in FlyteAdmin:
```failed to create workflow in propeller json: error calling MarshalJSON for type *v1alpha1.Inputs: Marshal called with nil```
Is this expected?

Hi <@U046DMNGBC7>!
Would you happen to have a minimum example of your task/workflow?

Looks like any task that take 0 parameter
```@task
def test() -&gt; str:
    return ""```

Well in my case, it’s a pod task
```@task(task_config=Pod(...))
def test() -&gt; str:
    return ""```

We do have tasks with no input, so this might be related to it being a pod task, could that be?

<@U046DMNGBC7> this is very unexpected. Can you say more about you're environment? Are you running on sandbox? flytekit version

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() -&gt; str:
    return "hello world!"

@workflow
def empty_pod_workflow() -&gt; 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 

Oh right, I believe we <https://github.com/flyteorg/flyteadmin/pull/495|addressed this here>.

<@U046DMNGBC7> do you know what version of flyteadmin you are running?
