Azure Functions独立工作者模型写入存储队列遇ObjectDisposedException错误

有人尝试过微软官方快速入门《使用Visual Studio Code将Azure Functions连接到Azure存储》的独立工作者模型（Isolated Worker Model）版本吗？

我实现了异步版本，初始运行正常，但提交4-5个请求（向队列添加消息）后出现以下错误，函数停止向队列插入消息：

几分钟后函数应用会恢复，但再次提交多个请求后会再次报错。

我发现问题与MultiResponse有关：若仅写入队列或仅返回HTTP响应则运行正常；而进程内模型（In-process Model）版本在同时发送队列消息和返回HTTP响应时运行完美。

以下是源代码：

namespace HttpTriggerAppVSC
{
    public class HttpExampleVSC
    {
        private readonly ILogger<HttpExampleVSC> _logger;

        public HttpExampleVSC(ILogger<HttpExampleVSC> logger)
        {
            _logger = logger;
        }
    
        [Function("HttpTrigger3")]
        public async Task<MultiResponse> HttpTrigger3(
            [HttpTrigger(AuthorizationLevel.System, "get", "post")] HttpRequestData req,
            FunctionContext executionContext, CancellationToken cancellationToken)
        {
            var logger = executionContext.GetLogger("HttpExampleVSC");
            logger.LogInformation("C# HTTP trigger function processed a request.");
    
            string name = req.Query["name"];
    
            string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
            dynamic data = JsonConvert.DeserializeObject(requestBody);
            name = name ?? data?.name;
    
            string message = string.IsNullOrEmpty(name)
                ? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
                : $"Hello, {name}. This HTTP triggered function executed successfully.";
    
            var response = req.CreateResponse(HttpStatusCode.OK);
            response.Headers.Add("Content-Type", "text/plain; charset=utf-8");
            await response.WriteStringAsync(message);
    
            // Return a response to both HTTP trigger and storage output binding.
            return new MultiResponse()
            {
                // Write a single message.
                Messages = new string[] { message },
                HttpResponse = response
            };
        }
    }
    
    public class MultiResponse
    {
        [QueueOutput("outqueue",Connection = "AzureStorageAccount")]
        public string[] Messages { get; set; }
        public HttpResponseData HttpResponse { get; set; }
    } 
}
