So we implemented the Crisis Communication App (https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/sample-crisis-communication-app) and we are using the Teams Connector Post to Post your own adaptive card as the Flow bot to a user.
We know the Teams Connector is in preview but we sometimes get a Status code 400 error when posting the card to a user:
{
"error": {
"code": "GraphUserDetailNotFound",
"message": "No user details with email or UPN 'user@domain.nl' were found in Graph."
}
}
Strange thing is that on MAY 14 one of the users failed, while on MAY 6 the Flow finished successfully for all 393 users including the failed user on MAY 14... is this a known issue that Graph Connection / Team Connector is buggy?
This must have been resolved since 2020.
