java.lang.IllegalArgumentException: Response cannot be null

I am facing the same type of error during AzureServiceBus onSuccess thread:

To do this, I have registered a message handler first:

azureServiceBusConnectionString = application.wirebox.getInstance( 'clientService' ).getAzureQueueConnectionString();
    azureServiceBus = getCloudService(
        {
            "vendorName" : "AZURE",
            "connectionString" : azureServiceBusConnectionString
        }, 
        {
            "serviceName" : "SERVICE_BUS"
        }
    );
    myQueue = azureServiceBus.getQueue( "queuecreatefortest3" );

    myQueue.registerMessageHandler({
        "autocomplete": "yes",
        "maxautorenewduration": "50M",
        "onSuccess": function( struct message ) {
            writeLog( text = "From onSuccess: " & serializeJSON( arguments ), type = "Information", file = "sushovan" );
            cfhttp( url="http://localhost/dev250/azureServiceBusQueueProxy.cfm" );
            writeLog( text = "From onSuccess: " & serializeJSON( cfhttp ), type = "Information", file = "sushovan" );
        },
        "onError": function() {
            writeLog( text = "From onError: " & serializeJSON( arguments ), type = "Information", file = "sushovan_error" );
        }
    });

Then to queue message, I have used this following code:

azureServiceBusConnectionString = application.wirebox.getInstance( 'clientService' ).getAzureQueueConnectionString();
    azureServiceBus = getCloudService(
		{
            "vendorName" : "AZURE",
            "connectionString" : azureServiceBusConnectionString
        }, 
		{
            "serviceName" : "SERVICE_BUS"
        }
    );
    myQueue = azureServiceBus.getQueue( "queuecreatefortest3" );

	getMessageResponse = myQueue.sendMessage({
		"messageBody": {
			"orderId": 434522,
			"order_id": 434522,
			"data": '{"dev_number":"250","order_id":434522,"amount":"0.01","prev_process_id":430022277,"transaction_tag":"430022277","txntype_id":2,"override":false,"mid_id":0}',
			"DEV_NUMBER": "250",
			"BATCH_ID": "",
			"processId": 430022277
		}
	});

When a queue message comes, it triggers `onSuccess`, here I can see first writeLog is working, next `cfhttp` is not working and giving the following error:

Post some code, maybe?
