Unexpected token in JSON

[kraxarn]

Sometimes, it seems like the JSON can't be parsed correctly and it then outputs the error SyntaxError: Unexpected token  in JSON at position x where x can be any number. Seems to be in between 1500 and 1800, but not sure.

I thought at first that this was because I ran out of API calls, but later the same day it can work just fine.

Same here.

SyntaxError
Unexpected token  in JSON at position 1826

Trace leads to line 55 at JSON.parse:

./node_modules/cleverbot-node/lib/cleverbot.js in Object.<anonymous> at line 55:35
            var chunks = [];
            res.on("data", function(data) {
              chunks.push(data);
            });
            res.on("end", function(i) {
              var body = Buffer.concat(chunks).toString();
              var responseBody;
              responseBody = JSON.parse(body);
              responseBody.message = responseBody.output; //for backwards compatibility
              this.state = responseBody.cs;
              cb(responseBody);
            }.bind(this));
        }.bind(this));
        req.end();

I reverted some code that should handle the bad chars in the response. There appears to be some issues with escape chars in JSON responses that I need to figure out. The fix I put in place is dirty, but it should work.
