感谢回复。已解决！ 需要增加内存缓存服务--services.AddMemoryCache()，以及管道要注册微信--weixinRegister.RegisterWorkAccount(senparcWeixinSetting.Value, "xxxxxxx");

这个方法不能定位到具体的问题，因为Execute内部会执行外部的自定义（包括委托和重写）的代码。

您可以先部署一个原版的 Sample 看一下效果，然后对照一下，比如 startup.cs 里面是否缺少了任何注册的代码。帮看您提供的日志，感觉是使用了内存缓存，但是没有注册。

这个方法：await messageHandler.ExecuteAsync(new CancellationToken());   报错的。这是senparc内置的1个方法，没法看到方法内部的报错情况吧。 我用异常捕捉(try,catch)，进不到catch里面。 详细的报错日志如下，看不出什么问题。

打断点调试或者靠日志输出看一下，什么对象为 null 了，应该是业务层面代码就能找到问题，SDK 内部都做判断了。

已添加的中间件：

//使用 企业微信 MessageHandler 中间件                                                 // -- DPBMARK Work
           app.UseMessageHandlerForWork("/WorkAsync", WorkCustomMessageHandler.GenerateMessageHandler,
                                        o => o.AccountSettingFunc = c => senparcWeixinSetting.Value);//最简化的方式
                                                                                                     // DPBMARK_END
