DescribeLayoutAsync throws a JsonReaderException

[odomsk]

I am new to using this package and I am receiving an error when using DescribeLayoutAsync. I am getting back records with the QueryAsync. Thank you in advance for any help!

Here is the code:

private async Task GetFields(string oVal) { var auth = new AuthenticationClient();

        await auth.UsernamePasswordAsync(consumerKeyVal, consumerSecretVal, userNameVal, passToken);
        var instanceUrl = auth.InstanceUrl;
        var accessToken = auth.AccessToken;
        var apiVersion = auth.ApiVersion;

        var client = new ForceClient(instanceUrl, accessToken, apiVersion);

        var response = await client.DescribeLayoutAsync<string>(oVal);  //oVal = "Lead"

    }

Here is the error:
