AttributeError: 'NoneType' object has no attribute 'get'

This error message is typically raised when you try to access an attribute or method of a variable that has a value of `None`. In this specific case, it seems that you are trying to call the `get()` method on a `NoneType` object, which is not possible.

To fix this error, you need to ensure that the variable you are calling `get()` on is not `None`. You can do this by adding an `if` statement to check if the variable exists before calling the method:

if my_variable is not None:
    my_variable.get()

Alternatively, you can initialize the variable with a default value, such as an empty dictionary or string, to avoid the `NoneType` error:

my_variable = {}  # empty dictionary
my_variable.get()  # will not raise an error
