Hello,
I am having a hard time to pass optional input param to tasks.
Ideally, I want the task either be passed the actual instance of the input param or None.
So I have :
```from sklearn.preprocessing import OneHotEncoder
@task
def transform(
    encoder: Optional[OneHotEncoder] = None, ...
)```
The workflow will do:
```  return transform(
   encoder=None, ...```
