Hey,
I’m having the same problem. What is this whitelisting you are talking about? Is it Flow XO feature or FB messenger? And where is it located? On the Facebook page?
I went around this by deleting all the urls from the request, but it didn’t help. It still gave me an error:
“(#100) Pages using Messenger Extensions must use https and not include any port.”
