Unable to create team using Microsoft Graph

Question

I couldn't create a team using Microsoft Graph.
I created the same code as the sample.
https://learn.microsoft.com/ja-jp/graph/api/team-post?view=graph-rest-1.0&tabs=csharp

Code I created:

var team = new Team  
            {  
                DisplayName = "My Sample Team",  
                Description = "My Sample Team’s Description",  
                AdditionalData = new Dictionary<string, object>()  
    {  
                {"******@odata.bind", "https://graph.microsoft.com/v1.0/teamsTemplates('standard')"}  
    }  
            };  
  
            await graphClient.Teams  
                .Request()  
                .AddAsync(team);  

I get an error when I run the program. What is the cause?

HI @Anonymous ,

As per your error description I can see you are using application permission to create a team and when issuing a request with application permissions, a user must be specified in the members collection. Please follow this documentation.

Use request body like below:

GraphServiceClient graphClient = new GraphServiceClient( authProvider );  
  
var team = new Team  
{  
	DisplayName = "My Sample Team",  
	Description = "My Sample Team’s Description",  
	Members = new TeamMembersCollectionPage()  
	{  
		new AadUserConversationMember  
		{  
			Roles = new List<String>()  
			{  
				"owner"  
			},  
			AdditionalData = new Dictionary<string, object>()  
			{  
				{"******@odata.bind", "https://graph.microsoft.com/v1.0/users('0040b377-61d8-43db-94f5-81374122dc7e')"}  
			}  
		}  
	},  
	AdditionalData = new Dictionary<string, object>()  
	{  
		{"******@odata.bind", "https://graph.microsoft.com/v1.0/teamsTemplates('standard')"}  
	}  
};  
  
await graphClient.Teams  
	.Request()  
	.AddAsync(team);  

Hope this helps.

J'ai une erreur au niveau de cette ligne il n'a pas accepté le Request() et si je l'élimine il ne marche pas aussi(j'utilise .net c# comme langage de programmation).

 await graphClient.Teams[createdTeam.Id].Members
     .Request()
     .AddAsync(user1);
