Unable to add Facebook channel to Microsoft Bot Framework

Question

I am unable to add Facebook Messenger as a channel to my bot. I'm receiving 400 error in the console and a fairly arcane error message (see the attached image). I have been able to successfully add DirectLine, Skype, and Slack.

From a troubleshooting perspective, I've tried the following:

• Create a new bot and try adding Facebook Messenger
• Create a new Facebook App
• Chrome, Safari, and Firefox all in regular and incognito modes
• Create a bot using a different Azure and Bot Framework account and a different Facebook account

Any help would be much appreciated.

Answer 1

I discovered the root issue here. The person who created the Facebook App did not associated it with a Facebook Page and generate the requisite Page Access Token. Once this was completed adding the Facebook Messenger channel worked correctly.

Thanks for pointing me in the right direction Bob Swager!
