使用自定义的FirstAzureSearchApp版本在处理您的请求时出现错误要求编号：1

问题描述

每当我尝试在“ FirstAzureSearchApp”上进行任何搜索时，都会发生错误。错误页面如下所示：“'处理您的请求时发生错误。''请求ID：1''开发模式''交换至开发环境将显示有关所发生错误的更多详细信息。 “不应在已部署的应用程序中启用开发环境，因为它可能导致异常显示的敏感信息显示给最终用户。对于本地调试，可以通过将ASPNETCORE_ENVIRONMENT环境变量设置为Development并重新启动应用程序来启用开发环境。 / p>

我尝试从“开发”更改为“生产”（如其他主题所建议），但我仍然得到相同的结果。使用Visual Studio Breakpoints，我在特定行的文件HomeController.cs上收到错误：model.resultList = await _indexClient.Documents.SearchAsync（model.searchText，parameters）;当我将异步方法更改为顺序方法时，没有得到该错误，但在一行上显示了错误：await RunQueryAsync（model）;第一次运行该行，它可以正常运行，但是在搜索时会循环返回，而第二次则给出上面出现的相同错误。
