[BUG] When producing message with Event Hubs async client - partitionId invalid, no available ones

[Amir-Qlik]

Description
In Event Hubs async client, producing a message to a partition with a valid partition Id "0" fails and the exception message lists an empty list of available partition Id's.

Exception
"partitionId is not valid. Available ones:"

To Reproduce

• Create a buffered producer client builder.
• Use the builder to create an async client.
• Create event data.
• Use the client to enqueue the event, specifying a partition Id in the send options.

Code Snippet

EventHubBufferedProducerClientBuilder builder = new EventHubBufferedProducerClientBuilder()
		.onSendBatchSucceeded(this::onBatchSucceed)
		.onSendBatchFailed(this::onBatchFailed)
		.connectionString(connectionString, hubName);

EventHubBufferedProducerAsyncClient producerClient = builder.buildAsyncClient();
EventData eventData = new EventData(("data_0").getBytes()).setMessageId("id_0");
producerClient.enqueueEvent(eventData, new SendOptions().setPartitionId("0")).subscribe(
		numberOfEvents -> {
			System.out.printf("There are %d events in the buffer.%n", numberOfEvents);
		}, error -> {
			System.err.println("Error occurred enqueueing events: " + error);
		},
		() -> {
			System.out.println("Event successfully enqueued.");
		});
