- When migrating a Private Channel in Teams, you may have to deal with the following error message:
“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.”.
- When migrating a General Channel inside a Private Group in Teams, you may have to deal with the following error message:
“Unable to find target Folder. Run the preprocessing task, please”
It is a Microsoft limitation.
Go to the Channel (Private or General) in the target via Teams, then click on the File’s Tab. This action will provide the SharePoint Site attached to the private channel.
Once this is done restarting the migration should fix the error.
