In my mobile app facebook login I'm asking for page_messages and page_messaging_subscription permissions.
When I try to send a message to a test user from a Node.js server, I get this error:
"(#100) Parameter error: You cannot send messages to this id"
The id is a app scoped user ID and the request is a POST request issued to this endpoint:
https://graph.facebook.com/v2.6/me/messages?access_token=SOME_PAGE_TOKEN
Note: The user has not interacted with the page before.
