I have integrated wit.ai with FB Messenger, but the results I get while talking to him via Messenger are not the same I get while talking to him in testing mode. Specifically the variables are not populated in the bot response. Although they are well populated when I test the bot in test mode within wit.ai site.
I have attached 2 screenshots as you can see the {contact} variable (in this case 'Nick') is not added in the response text. Can you please suggest why is this happening? As I assume the communication between Messenger and wit.ai is pure text, and there should not be any other handling on the Messenger side (for example manually populating the variables).
