Hello , i faced an issues when intégrating my chatbot to facebook messenger , the issue was “The Callback URL or Verify Token couldn’t be validated. Please verify the provided information or try again later.” the steps i followed are : 1- creating a new app (facebook dev) linked it with a facebook page 2- generating the page token and secret key , add them to credentials.yml
-
I ran rasa server using rasa run --credentials credentials.yml
-
I ran ngrok server …
-
this is what i got while verifying the callbacks url
