"VarnameRetrievingError: Unable to retrieve the ast node." / "VarnameRetrievingError: Cannot retrieve the node where the function is called."

OK, so I'm running this on Windows 11 so maybe that is part of the problem? Anyway, I don't get very far along in your example usage from the README before I get an error. I get similar errors when I'm just poking around, doing almost anything I would want this module for.
`

from varname import varname
def function():
... return varname()
...
func = function() # func == 'func'
Traceback (most recent call last):

raise VarnameRetrievingError("Unable to retrieve the ast node.")
varname.utils.VarnameRetrievingError: Unable to retrieve the ast node.

So here is my own example to show the partial functionality of the module:
