When I create a new team with the graph API below:
The team gets successfully created and also all other artefacts like SharePoint site. But when I select the channel “General” and click on the three dots and the link called ‘Open in SharePoint', I always gets the following pops up. 
The expected behavior would be, that I can directly open my SharePoint site of my team. But I can fix this behavior later, when I click on the Files tab. After I done that the link ‘Open in SharePoint' works as expected. I tested this on the web client and the desktop client. Both worked the same. Also if creating a team manually, this issue will not reproduce.
