Thanks for the video. Now it is clear to me what has happened and why copy
solves the problem.

params = {} if params is None else params.copy()
has solved the problem.
I have provided just a toy example here. Execute method actually takes
dict[str, List]. List contains objects. Each object has two properties, so I
have a logic that analyzes these properties and returns None or List as a

Hi,
consider this example:
from typing import Dict, List
class chk_params:
def execute(self, params: Dict[str, List] = None):

params[k] = [val + 10 for val in v]
return params.values
