I am looking to send an email confirmation when a planner task has been completed to the original task creator, when a planner project is completed. Flow recently added the "When a task is completed trigger" But the supplied. fields are only Created By User Id and Created B User Display Name. So somehow I need to convert this into an email address from what I can tell.
My plan was to use the display name and lookup users and find the matching display name to the list of office 365 users. When I tried to implement this, every single user didn't match so I backed up and just had flow send me the name of the Created By User Display Name on completion and the field is null.
What am I doing wrong why is this value null. Any insights as to why planner doesn't know the task creator?
