Shared Channel Creation

[ncangeles1995]

When creating a shared channel, a channel is not being returned as the result. Furthermore, the response headers do not contain the channel ID as it does for team creation.

Thanks for raising this @ncangeles1995

Any chance you can share more details/code sample you are using to help us understand this better?

Sure, see below is the code sample I am using:
var requestBody = new Channel
{
DisplayName = channelName,
Description = channelName,
MembershipType = ChannelMembershipType.Shared,
Members = new List
{
new ConversationMember
{
OdataType = "#microsoft.graph.aadUserConversationMember",
Roles = new List
{
"owner"
},
AdditionalData = new Dictionary<string, object>
{
{
"user@odata.bind" , $"https://graph.microsoft.com/.default/users({userId})"
}
}
}
}
};
var res = await graphClient.Teams[teamId].Channels.PostAsync(requestBody);

As the documentation shows, the API will not return a value for this specific API call.
https://learn.microsoft.com/en-us/graph/api/channel-post?view=graph-rest-1.0&tabs=http#example-5-create-a-shared-channel-on-behalf-of-a-user

You can however read the header in the response as documented in the guide.
https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/dev/docs/upgrade-to-v5.md#native-response-object

        var nativeResponseHandler = new NativeResponseHandler();
        var res = await graphClient.Teams["teamId"].Channels.PostAsync(requestBody, requestConfiguration => requestConfiguration.Options.Add(new ResponseHandlerOption() { ResponseHandler = nativeResponseHandler }));
        var responseMessage = nativeResponseHandler.Value as HttpResponseMessage;
        var contentLocation = responseMessage.Content.Headers.ContentLocation.ToString();

        var responseMessage = nativeResponseHandler.Value as HttpResponseMessage;
        var contentLocation = responseMessage.Content.Headers.ContentLocation.ToString();

This seems to be throwing an error because ContentLocation is null. Is this a bug?

Any chance you have any luck logging the headers to see if returns the Location header instead?

            var responseMessage = nativeResponseHandler.Value as HttpResponseMessage;
            Console.WriteLine("Status code: "+ responseMessage.StatusCode.ToString());
            if (responseMessage.IsSuccessStatusCode)
            {
                foreach(var header in responseMessage.Headers)
                    Console.WriteLine("Header: "+ header.Key + " Value: " +header.Value.First());
                foreach (var header in responseMessage.Content.Headers)
                    Console.WriteLine("Header: " + header.Key + " Value: " + header.Value.First());
            }

 var nativeResponseHandler = new NativeResponseHandler();

No luck, the header seems to only have the Teams ID that was passed in to create the Channel. Nothing that looks to be the Channel ID is returned.
