  scrapy/utils/misc.py:249: DeprecationWarning: ast.NameConstant is deprecated and will be removed in Python 3.14; use ast.Constant instead
      value is None or isinstance(value, ast.NameConstant) and value.value is None
  ```
  
  Also, if I understand it correctly `isinstance(value, ast.NameConstant)` is always False, as `ast.NameConstant()` returns an `ast.Constant` instance, so I wonder if this case is covered by a test.
