AttributeError: 'str' object has no attribute 'decode'. Did you mean: 'encode'? parse_qsl seems to return list of string pairs already.

https://docs.python.org/3/library/urllib.parse.html

Parse a query string given as a string argument (data of type application/x-www-form-urlencoded). Data are returned as a list of name, value pairs.

This is the description I could find on the official docs. I get the same issue

Fixed it with #103
