Google Dialogflow Messenger Integrations not working

Question

I created a Dialogflow Integration. Then I copy the Script statements to my skeletal HTML. The intent works at this point when I click the "Try it now' button; however, when I execute it on the web, I just get the prompt icon. I do not get a prompt. It behaves as though I am working with an empty intent. The Intent works just fine in the dialogflwo interface.
