   Hi, I faced the same issue when I am using 2.2.4. I added a type validation of boolean for a parameter then when clicking the dag page, it shows error:
   
   > Python version: 3.7.12
   Airflow version: 2.2.4
   Node: 3d45b1bc1955
   Traceback (most recent call last):
     File "/home/airflow/.local/lib/python3.7/site-packages/airflow/models/param.py", line 62, in __init__
       jsonschema.validate(self.value, self.schema, format_checker=FormatChecker())
     File "/home/airflow/.local/lib/python3.7/site-packages/jsonschema/validators.py", line 934, in validate
       raise error
   jsonschema.exceptions.ValidationError: 'NoValueSentinel' is not of type 'null', 'boolean'
   Failed validating 'type' in schema:
       {'type': ['null', 'boolean']}
   On instance:
       'NoValueSentinel'
   
   any ideas?
