Is provisioning Teams teams and channels using the Graph API supposed to be unreliable?

Hi @Ian Simpson

Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. Since your issue is more related to Teams API development. So I will also add Teams development tag to your thread. Thanks for your understanding!

I have been struggling with this the last few days. I've tested on 2 tenants with the same behavior. I did ~20 test teams/channels, not a single one worked.

The issue is referenced in this doc-

https://zcusa.951200.xyz/en-us/graph/api/channel-post?view=graph-rest-1.0&tabs=http

• When you create a private/shared channel, the SharePoint site might fail to provision. If the site fails to provision after 5 minutes, use the Get filesFolder API to trigger provisioning.

Steps to reproduce. I'm using power automate, but it does the same thing via Graph Explorer.

-Create team via HTTP action using graph api or Send a MS Graph API Request action.

-Primary channel sharepoint site fails to provision unless you manually click on the files tab

POST

https://graph.microsoft.com/v1.0/teams

{
   "template@odata.bind":"https://graph.microsoft.com/v1.0/teamsTemplates('standard')",
   "displayName":"testxyz",
   "description":"Client team for x",
   "members":[
      {
         "@odata.type":"#microsoft.graph.aadUserConversationMember",
         "roles":[
            "owner"
         ],
         "user@odata.bind":"https://graph.microsoft.com/v1.0/users('flowbot@x.com')"
      }
   ]
}

-Create private channel via HTTP action using graph api

-Private channel sharepoint site fails to provision unless you manually click on the files tab

POST

https://graph.microsoft.com/v1.0/teams/{teamid}/channels

{
  "@odata.type": "#Microsoft.Graph.channel",
  "membershipType": "private",
  "displayName": "xInternal",
  "description": "A private channel",
  "members": [
    {
      "@odata.type": "#microsoft.graph.aadUserConversationMember",
      "user@odata.bind": "https://graph.microsoft.com/v1.0/users('flowbot@x.com')",
      "roles": [
        "owner"
      ]
    }
  ]
}

The /filesFolder trick I've seen referenced does not appear to do anything. I can let that go for 30+ minutes with no movement, but as soon as I click the Files tab in the channel, it'll be ready in ~1 minute.

(This step starts after private channel creation, plus a 5 minute delay)

Putting me in an awkward spot, as I've been hired to automate this process and there doesn't appear to be a valid workaround anymore.

@Nivedipa-MSFT Please let me know if you need additional information.
