listing Microsoft Teams tabs always returns 404

Question

I've been trying this scenario on a couple of different tenants so far:

• use an existing team or create a new one through the UI
• add a tab (let's say OneNote) to a channel
• query the list tabs endpoint (through graph explorer)

I always get a 404 response. If I replace in my query tabs by messages I get the messages.

In terms of permissions I have the default graph explorer one + Group.Read.All.

Here is the latest request Id I got 2a180611-b637-4aa4-be27-9e42cbb27ab9 on tenant dev2tolead12. (GET https://graph.microsoft.com/beta/teams/7471ee8d-0ed3-4f22-80ee-3b513e42e6ac/channels/19:9a0544b274654ef8ac97761ebd91b471@thread.skype/tabs)

My question: what am I missing for this request to work?

Answer 1

Sorry, we thought we had deployed the tabs API to all tenants, but had actually deployed it to only some of them – this has been fixed.

Answer 2

The endpoint started working in my tenants today. My guess is Microsoft fixed something recently
