Issue with Create Private Channel via Power Automate?

[sngbcn]

I'm creating a flow to provision Teams with a certain structure, a template, but when I get to the point of creating the private channel there is no way to get it right. I'm always trying to do the same using the graph explorer but when I paste the json body in power automate there's an error message.

This is the code that works in the Graph Explorer:

POST https://graph.microsoft.com/beta/teams/{group_id}/channels
Content-type: application/json

{ "membershipType": "Private",
  "displayName": "Confidential info",
  "members":[{    
           "@odata.type":"#microsoft.graph.aadUserConversationMember",
           "user@odata.bind":"https://graph.microsoft.com/beta/users('<userID>')",
           "roles":["owner"]
            }]
}

and this is the request body according to the documentation:

POST https://graph.microsoft.com/beta/teams/{group_id}/channels
Content-type: application/json

{
  "@odata.type": "#Microsoft.Teams.Core.channel",
  "membershipType": "private",
  "displayName": "My First Private Channel",
  "description": "This is my first private channels",
  "members":
     [
        {
           "@odata.type":"#microsoft.graph.aadUserConversationMember",
           "user@odata.bind":"https://graph.microsoft.com/beta/users('{user_id}')",
           "roles":["owner"]
        }
     ]
}

I added the code from graph explorer directly to a flow but when I run it the following error message appears:

{
  "error": {
    "code": "BadRequest",
    "message": "channel cannot be null.\r\nParameter name: channel",
    "innerError": {
      "request-id": "<id>",
      "date": "<date>"
    }
  }
}

Any ideas?

Thanks!

Hi!

Haven't tried myself but this article describes a similar successful scenario

https://myteamsday.com/2020/01/03/create-private-channel-graph-api/

Now, in the article's comments thread a similar issue is described

Hope this helps

In fact I've tried a few approachs:

- @odata.bind as a string inside a variable

- the whole json inside a variable 

- the double @ sign in front if odata.bind

all of them with no positive results

Hi @sngbcn, please show your flow.

@VictorIvanidze this is the whole flow. I also add an image of the error step and message.

hi @VictorIvanidze @efialttes I have already followed the advice in that website without any luck. As I commented I have accomplished creating a new channel through Graph Explorer but the same code fails when running a flow...

Have you tried it even with a basic flow? Do you see anything missing in the http request?
