OData Integration Services

Hi Friends,

              I am trying to consume the new Dynamics AX7 OData endpoint from a .Net console applications, I can                 see that the authentication is going fine but whenever I try to get the results on my application it ends                 with an Unauthorized error. Any idea on what could be the cause or hos to get a more detailed              information (logs)?

This is the code that throws the error at line,

static void Main(string[] args)
{
Uri oDataUri = new Uri(ODataEntityPath, UriKind.Absolute);
var context = new Resources(oDataUri);

context.SendingRequest2 += new EventHandler<SendingRequest2EventArgs>(delegate (object sender, SendingRequest2EventArgs e)
{
var authenticationHeader = OAuthHelper.GetAuthenticationHeader();
e.RequestMessage.SetHeader(OAuthHelper.OAuthHeader,
authenticationHeader);
});

foreach (var legalEntity in context.LegalEntities.AsEnumerable())
{
Console.WriteLine("Name:{0}", legalEntity.Name);
}

Expection occurs like :

An unhandled exception of type
'Microsoft.OData.Client.DataServiceQueryException' occurred in
Microsoft.OData.Client.dll

Additional information: An error occurred while processing this request.

My Cilent Configuration is like :

public static CilentConfiguration OneBox = new CilentConfiguration()
{
UriString = "usnconeboxax1aos.cloud.onebox.dynamics.com",
UserName = "***",
Password = "pass***",
ActiveDirectoryResource =
"usnconeboxax1aos.cloud.onebox.dynamics.com",
ActiveDirectoryTenant =
"login.windows.net/.../authorize",
ActiveDirectoryClientAppId = "cb5c660e-ad09-4895-90a0-778786cdf956",
ActiveDirectoryClientAppSecret =
"lMLjJm0tCgUGvUs6LJtzWscKTpJZBMgkCng7es2BDkY=",

and my error page is ,
