I have a Flow to approve documents in a SharePoint document library. In the "Start an approval" action, if the "Assigned To" field is set to my own named email address it works great. However, if I change the "Assigned To" field to a shared mailbox email address, I get the following error. Any ideas on this?
BadRequest. The request failed. Error code: 'InvalidApprovalSubscribeRequestAssignedToMissing'. Error Message: 'Required field 'assignedTo' is missing, empty, or contained no valid users.'.
Screenshot as follows (following action step fails as well).
Thanks
