This project was written in 2014, but when I last tested it, it seemed to work when I restricted the game mode to gen6randombattle.

The error that your receiving might be due a change in how Showdown communicates with clients. When I get the chance, I'll take a look and see if it's an easy fix or not.

Updating the bot to work with newer Pokemon and battle rules might be more complicated.
