When migrating a Private Channel in Teams, you have noticed the following error:
“FATAL_ERROR : Unable to connect to target teams: Unable to generate SkypeToken to Provision Channel SP site. Error: Object reference not set to an instance of an object.”.
We can’t provision the SharePoint Site of the Team’s Private Channel. It is a Microsoft limitation.
Go to the Private Channel in the target via Teams, then click on the File’s Tab (“Fichiers” below). This action will provision the SharePoint Site attached to the private channel.
Once this is done restarting the migration should fix the error.
