Microsoft Graph not returning Service Principals inside group

Question

I have a security group in Azure Entra ID that contains 6 service principals and a user (I added that user just for testing purposes).

I want to get the names of the Service Principals from an Azure Functions app by making a call to the "Groups[<id>].Members" Microsoft Graph endpoint. However, I am only able to get the user which is not the result I want.

My call is the following:

I tried using QueryParameters.Expands = new string[] { "members" } as stated in the docs but it doesn't work. It returns an error "Could not find a property named 'members' on type 'microsoft.graph.directoryObject'".

List group members

Hi @Ivan Ferro

The blue area of the documentation has an important note on this.

So try using this API on the beta endpoint or use the /groups/{id}?$expand=members API instead.

var result = await graphClient.Groups["{group-id}"].GetAsync((requestConfiguration) =>
{
	requestConfiguration.QueryParameters.Expand = new string []{ "members" };
});

Hope this helps.
