Azure Graph API calls throwing Exception The context is already tracking a different entity with the same resource Uri

Question

We are using Azure Graph API client library version 2.1.1.0. Our application tries to validate the user roles at the time of login. While doing this ad client. Following call seems to be throwing an exception. Any help in this regard is highly appreciated.

Call:

       adClient.Users
            .Expand(_ => _.MemberOf)
            .Where(_ => _.ObjectId == objectId)
            .ExecuteAsync()
            .Result;
       adClient.DirectoryRoles
            .Expand(_ => _.Members)
            .ExecuteAsync()
            .Result;.
