'NoneType' object is not callable

This error occurs when you try to call a method or function on a variable that is of type None. In other words, you are trying to use a variable that has no value assigned to it.
To fix this error, you need to make sure that the variable you are using has a value assigned to it before you try to call a method or function on it. You can also check if the variable is None before calling any method or function on it to avoid this error.
Here's an example:
```
my_variable = None
if my_variable is not None:
my_variable.some_method()
else:
print("my_variable has no value assigned to it.")
```
In this example, we check if my_variable is not None before calling the some_method() method on it. If my_variable is None, we print an error message instead.
