Re: [I] `airflow.Param` fails to get the default value of `array`. [airflow]

   I've noticed that 
   if I pass a serialized value as a `json` string instead of a `python` 
object, 
   I can get the default value.
   
   Does the default value for `airflow.Param` only accept `json` strings?

   from airflow.models.param import Param

       params={
           "has_default_list": Param(
               default="[]", items={"type": "string"}, title="Has default 
list", type="array"
           )
       },
   )
   def render_test() -> None:
       EmptyOperator(task_id="empty_task")
   
   
   render_test()
   ```
