ApiTypeError in last version #200

Im trying to get this to work but i am receiving many different errors. Is it possible that the version is outdated?

I got this error applying the example in the readme:

raise get_type_error(input_value, path_to_item, valid_classes,
lob_python.exceptions.ApiTypeError: Invalid type for variable 'description'. Required value type is one of [NoneType, str] and passed type was ResourceDescription at ['description']
