I was getting TypeError: Cannot read property 'indexOf' of null when running how2 cat (described further at #86). It may be a little hacky though :)

Thank you @jamesalbert. Yes, it seems hacky and we should probably move to a Promise-based approach. I am planning to refactor the code, but in the meanwhile this fix is totally acceptable.
