Description
We are currently investigating an issue where posting to new messaging threads results in an error. The error looks like this:

{
"error": {
"message": "(#551) This person isn't available right now.",
"type": "OAuthException",
"code": 551,
"error_subcode": 1545041,
}
}

Sending messages in pre-existing threads does not currently seem to have this issue
