AttributeError: 'str' object has no attribute 'name' in language attribute

What happened ?

When I tried to run the program with the following command, an error is thrown when it tries to download the manga titles like One Man Punch or One Piece:

python -m mangadex_downloader "d8a959f7-648e-4c8d-8f23-f1f3f8e129f3" -ngn -uct -noc --delay-requests 6.0 --save-as pdf-volume --path ./manga/

I also tried to append the --lang "English" at the end of the command and I received the same result.

python -m mangadex_downloader "a1c7c817-4e59-43b7-9365-09675a149a6f" -ngn -uct -noc --delay-requests 6.0 --save-as pdf-volume --path ./manga/

Error:
