Graph api v1.0/teams Post suddenly doesnt allow tab configuration in json template

Question

Hello,

I have been using the v1.0/teams endpoint of the graph api to create teams by using json templates.
This worked fine untill friday 19/02/2021 and then it suddenly stopt working.
As i have discovered it is the tab configuration that causes the error , because when i try a template without any tab configuration it works just fine.

note: this error can be reproduced in the graph explorer

This is an example of a template i use:

{
"template@odata.bind": "https://graph.microsoft.com/v1.0/teamsTemplates('standard')",
"group@odata.bind": "https://graph.microsoft.com/v1.0/groups('groupId')",

This has also been reported here, see my answer there. If you can continue without tabs, I suggest you continue using the API without them for now. I believe this is being looked at and I will post here new info that I find.
