After editing an action with the debug mode where I put in the "Domain" field, the URL of my filter I wanted to default instead of a Python expression I guess ...
Here is the Error message I have when I click on the tab where I edited the action:
UncaughtPromiseError > EvalError
Uncaught Promise > Can not parse python expression: (&view_type=kanban&cids=1&menu_id=418)
Error: Token cannot be parsed
EvalError: Can not parse python expression: (&view_type=kanban&cids=1&menu_id=418)
Error: Token cannot be parsed
