Exception: KeyError: 'content-type'

So I'm getting the error "KeyError: 'content-type'" when I try to get unread messages. I have always used PyTextNow and I know for a fact that this has worked before, but now it isn't. Can someone tell me why, even though this project hasn't been updated in a while?

After some tinkering, I found out that line 10 of mulitmediamessage will request and return {"error":"Missing Querystring Params"}. If I remove line 13 and 14 of that file, it works again, but I really don't want to break anything
