【问题描述】：

我最近正在开发一个使用 ServiceBus 工作的 Azure 函数。但是，当我们在开发环境中进行测试时，它可以完美运行，当我们投入生产时，会发生一些错误并生成我无法调试和理解的堆栈跟踪器，有人可以帮助我吗？我在下面留下堆栈跟踪供您查看。

【参考方案1】：

RpcException 是一个非常普遍的错误，可能存在潜在问题。

当函数执行失败并且异常以Microsoft.Azure.WebJobs.Script.Workers.Rpc.RpcException : Result: Failure 开头时，看起来这应该是平台错误，而在几乎所有情况下，它都是来自用户代码的异常堆栈失败。

尝试重启函数应用。
