我正在尝试创建一个简单的V2 Azure函数。它可以是匿名身份验证级别，因为它将由API Management保护。

构造器和函数如下所示：

        public ProvideOfsPortfolioData(IMediator mediatorService,IInstrumentationService instrumentationService,ILogger<ProvideOfsPortfolioData> logger)
        {
            _mediatorService = mediatorService;
            _instrumentationService = instrumentationService;
            _logger = logger;
            _typeName = "Interfaces.Ce.Presentation.AzureFunctions.ProvideOfsPortfolioData";
        }

        [FunctionName("ProvideOfsPortfolioData")]
        public async Task<IactionResult> Run(
            [HttpTrigger(AuthorizationLevel.Anonymous,"get",Route = null)] HttpRequest req)
        {
            _logger.LogInformation($"{_typeName}.Run] - Started");
        }

当我尝试通过在VS2019中按F5进行调试时，在控制台窗口中出现以下错误：

An unhandled host error has occurred.
microsoft.AspNetCore.Authentication.Core: No authentication handlers

AddAuthentication().Add[SomeAuthHandler]("WebJobsAuthLevel",...)?.
