When you return a webhook message to Twilio, you need to make sure it's valid TwiML, which in essence is just a set of XML verbs Twilio uses.

If you're responding to an SMS message for example, you would return TwiML as follows:

    Thanks for getting in touch, I'll call you later

You can test the code above by changing the configuration of your number to point to this url and you should stop seeing the errors.

If you generating the TwiML yourself, you need to make sure that the page's MIME type is text/xml.

Hope this helps you out.
