Unable to List channels with Graph API

[mhodovnaiuk]

Hi,

I am trying to list channels with Graph API by sending
`GET https://graph.microsoft.com/beta/groups/{id}/channels` (`GET https://graph.microsoft.com/v1.0/teams/{id}/channels` does not work as well).

The response is:

{
  "error": {
    "code": "BadRequest",
    "message": "Failed to execute Skype backend request GetThreadS2SRequest.",
    "innerError": {
      "request-id": "74635040-5d24-4399-9954-2c15643db862",
      "date": "2019-03-04T13:20:37"
    }
  }
}

At the same time `GET https://graph.microsoft.com/v1.0/me/joinedTeams` works well. I have tried to create a new team and pass its id, but the result is the same. Is this MS issue or something wrong with my setup/request?

Thanks.

How do you insert the id?

[#3]

Thank you for your reply.

I take it from the `https://graph.microsoft.com/v1.0/me/joinedTeams` response and put it to next call: `https://graph.microsoft.com/v1.0/teams/a72df4a4-bbb2-4ce8-9264-fc58df4bcf31/channels`. I am using postman.

It looks like this is definitely not an id issue: I am able to get messages with `https://graph.microsoft.com/beta/teams/a72df4a4-bbb2-4ce8-9264-fc58df4bcf31/channels/19:f778a09939b4...` (I have copied channel id from the web application). I am wondering are there any limitations for the free version of MS Teams or something like this.

UP. Still facing this issue.

Can you Please go to GraphExplorer https://developer.microsoft.com/en-us/graph/graph-explorer add the Teams Category and login with your Office 365 Credentials. Try the Channels of a Team which I am a member of.  which eventually is https://graph.microsoft.com/v1.0/teams/{ID}/channels. I tested just now it works fine... 

[#7]

I am doing this on an E3...The Graph explorer can help you see if the API is working for your id.

Thank you for your reply. I have signed in with the same credentials (to graph-explorer and teams.microsoft.com). I do have some teams, but GET https://graph.microsoft.com/v1.0/me/joinedTeams returns me

{
  "error": {
    "code": "ResourceNotFound",
    "message": "Resource not found.",
    "innerError": {
      "request-id": "75aba59f-1b7b-4edb-b923-ca4cca4f4dbe",
      "date": "2019-03-07T21:39:10"
    }
  }
}

Please ignore my previous reply. I found the reason on SO why I am getting 404. Trying to resolve it.

[#10]

Thanks. It turns out to be a problem with my account: it was some old account and when I logged in with it to Graph Explorer I realized that some request does not work as expected.

I have created a new account and sign into Microsoft developer program. Everything works fine now.

@Maruthi Gadde 

I'm having the same issue. I can't create another account.

I go to the graph-explorer link you give, use the Channels of a Team which I am a member of, and I get the same respone.

{
"error": {
"code": "AccessDenied",
"message": "Failed to execute Skype backend request GetThreadRequest.",
"innerError": {
"request-id": "870a5389-4f23-44d7-86aa-6d198dd59751",
"date": "2019-06-21T06:14:03"
}
}
}

I do have the Group.Read.All and Group.ReadWrite.All both as application and delegated permission.

HI, @mhodovnaiuk,
Did you found a solution for this issue ? I have same responce to the same request:

GET https://graph.microsoft.com/v1.0/teams/994b7a25-c7ab-41a4-89ac-1ef122af6c70/channels

{
"error": {
"code": "AccessDenied",
"message": "Failed to execute Skype backend request GetThreadS2SRequest.",
"innerError": {
"request-id": "2fa1089b-77cb-4dcc-a8f9-9d32649c6653",
"date": "2019-10-21T17:32:42"
}
}
}

team_id (994b7a25-c7ab-41a4-89ac-1ef122af6c70) is copypasted from Azure portal UI, and I have the Group.Read.All and Group.ReadWrite.All both as application and delegated permission. 

Request
GET https://graph.microsoft.com/v1.0/users

works fine.

Solved by changing from 'authorization_code' to 'client_credentials' while requesting access token.

[#14]

Is this issue fixed? I am still facing the issue in getting ms teams channels only for non azure admin users
https://graph.microsoft.com/v1.0/teams/team_id/channels

{

  "error":{

    "code":"Forbidden",
    "message":"Failed to execute Skype backend request GetThreadRequest.",
    "innerError":{

      "date":"2020-07-29T21:09:30",
      "request-id":"3c6e8d8a-fdff-433b-877e-c785690837f5"

}

}

}
Provided the right delegated permissions Group.ReadWrite.all and Directory.Read.all permissions and granted admin consent.

[#15]

For anyone who stumbles across this in the future, you cannot list channels for teams that the authenticated user is not added to.

After scouring the documentation I don't think this is explicitly stated anywhere but holds true.
