TypeError NoneType object is not callable

This error message indicates that you are trying to call a method or function on an object that is of type None.

For example, if you have assigned a variable to a function that returns None instead of a function object, attempting to call that variable as a function will result in this error.

To fix this error, you should check that the object you are calling is not None and that it is actually a callable function or method. If it is not, you may need to reassign the variable to a valid function or object that can be called.
