Intune Data warehouse error

Hi,

Thanks for the fast response! I added the delegated "get_data_warehouse" permission, and it still returns the same error. The goal is also to use the application without a signed in user, so I thought I needed application permissions instead of delegated permissions?

Here are the permissions my app registration currently has has:

And at the moment I use this code to retrieve the token:

public partial class AuthWrapper
{
    const string ClientId = "x";     
	const string tenant = "y";
	const string authority = ("https://login.microsoftonline.com/" + tenant);
	const string resourceId = "https://fef.msub05.manage.microsoft.com/";
	private string token = "";
    IConfidentialClientApplication app;
	public AuthWrapper()
    {
        token = GetAuthenticationResult().Result.AccessToken;
    }

    private async Task<AuthenticationResult> GetAuthenticationResult()
	{
		var app = ConfidentialClientApplicationBuilder.Create(ClientId).WithClientSecret("z").WithAuthority(authority).Build();
		var authResult = await app.AcquireTokenForClient(
        new[] { $"{resourceId}/.default" }).ExecuteAsync().ConfigureAwait(false);
		return authResult;
    }

    public string fetchUrl(string url)
    {
        HttpClient client = new HttpClient();
		client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
		client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
		HttpResponseMessage response = client.GetAsync(url).Result;
		return response.Content.ReadAsStringAsync().Result;
    }
}

@Timo De Grande, Thanks for the reply. I find it still not working after we add data warehouse permission. For the code, I am not familiar, I suggest open premier case to look into it.
