amqp:internal-error trying to implement renew-lock for ServiceBus

Hi, I am trying to implement the renew-lock mentioned in #164 .

I am using the documentation from the page referenced on renew-lock.

If I call the renew-lock on a partitioned topic, I get the following message:

This SDK does not support operation ‘com.microsoft:renew-lock’ for an entity with partitioning enabled. Please use a newer version of the SDK

If I try to renew a lock on a non-partitioned topic, I get the following:

errorCondition: {amqp:internal-error} statusCode: 0x000001f4 The service was unable to process the request; please retry the operation.

Here’s some sample code to recreate. I am hoping it is something simple, like possibly in the way that I have the BodySection implemented. Do you have any pointers? Or is renewing a lock on Service Bus through this library simply not possible? If it is possible, will we be able to renew a lock on a partitioned topic as well? Maybe via implementing x-opt-partition-key somehow?

Thanks for your time…

public static async Task RenewLock(string connectionString, Message message, string topic, string subscription, int lockDurationMilliseconds)
{
    var lockToken = new Guid(message.DeliveryTag).ToString();
    var entityAddress = $"{topic}/Subscriptions/{subscription}";
    var managementNodeAddress = $"{entityAddress}/$management";
    var renewLockSenderAddress = $"{subscription}-renew-lock-sender";
    var renewLockReceiverAddress = $"{subscription}-renew-lock-reply-to";

    var senderAttach = new Attach()
    {
        Source = new Source() { Address = renewLockSenderAddress },
        Target = new Target() { Address = managementNodeAddress }
    };

    var recieverAttach = new Attach()
    {
        Source = new Source() { Address = managementNodeAddress },
        Target = new Target() { Address = renewLockReceiverAddress },
    };

    var connection = await Amqp.Connection.Factory.CreateAsync(new Amqp.Address(connectionString));
    var renewLockSession = new Session(connection);
    var renewLockSenderLink = new Amqp.SenderLink(renewLockSession, "renew-lock-sender", senderAttach, null);
    var renewLockReceiverLink = new Amqp.ReceiverLink(renewLockSession, "renew-lock-receiver", recieverAttach, null);

    Console.WriteLine(message.Properties.MessageId);

    var renewLockMessage = new Message()
    {
        ApplicationProperties = new ApplicationProperties(),
        Properties = new Properties()
        {
            MessageId = message.Properties.MessageId,
            ReplyTo = renewLockReceiverAddress
        },
        BodySection = new Data() { Binary = Encoding.UTF8.GetBytes($"['map',['string', 'lock-tokens'], ['array', 'uuid', '{lockToken}']]") }
    };
    renewLockMessage.ApplicationProperties["operation"] = "com.microsoft:renew-lock";
    renewLockMessage.ApplicationProperties["com.microsoft:server-timeout"] = lockDurationMilliseconds;

    await renewLockSenderLink.SendAsync(renewLockMessage);

    var renewLockResponse = await renewLockReceiverLink.ReceiveAsync();

    await renewLockSenderLink.CloseAsync();
    await renewLockReceiverLink.CloseAsync();
    await renewLockSession.CloseAsync();
    await connection.CloseAsync();
}

LockToken is of type Guid, so the line to create the lockToken should be,

    var lockToken = new Guid(message.DeliveryTag);

The request body is AmqpValue containing a map. It should be created like this,

        BodySection = new AmqpValue() { Value = new Map() { { "lock-tokens", new Guid[] { lockToken } } } }

… and now it works in both scenarios (with or without x-opt-partition-key). I could consistently recreate the issue up until about an hour ago. Now it just started working. Odd… thanks for the help!
