            [Blob("order-processed/{rand-guid}.json")] out string acceptedQueueItem,
            ILogger log)
        {

            Order data = JsonConvert.DeserializeObject<Order>(myQueueItem);

            [QueueTrigger("order-new", Connection = "AzureWebJobsStorage")] string myQueueItem,
            [CosmosDB(databaseName: "MyCosmosDB", collectionName: "Orders",
            ConnectionStringSetting = "MyCosmosDBConnectionString")]IAsyncCollector<dynamic> myCosmosItem,
            ILogger log)
        {
