Hello AnavSilverman​ NancyatMSFT​ 

I have few automatic process running with Power Automate to create/update task in planner. I have a specific process to add comment to a task using groups endpoint Graph API (POST https://graph.microsoft.com/v1.0/groups/{idgroup}/threads/{idthread}/reply).

POST https://graph.microsoft.com/beta/planner/tasks/{taskid}/messages seems to work to add message to the new chat feature but planner endpoint isn't accessible from Power Automate. I must use groups endpoint. I found this end point with groups 

POST https://graph.microsoft.com/beta/groups/{group-id}/planner/plans/{plannerPlan-id}/tasks/{plannerTask-id}/messages but It gives me error "

Write requests are only supported on contained entities or navigation properties with bindings." What can I do ?
