的documentation告诉我们，一个解析器具有这种形式：如何在graphql apollo-server突变解析程序中发出错误信号？
fieldName: (obj, args, context, info) => result
而这结果是null或undefined如果“对象找不到”。
其他错误怎么样 - 例如，如果访问未被授权？
您似乎无法直接“返回”错误，因为结果必须与模式匹配。
我试过在解析器中抛出一个异常，这几乎是正确的：客户端得到一个ApolloError异常消息：很棒。但是apollo-server发出一个堆栈跟踪，就好像这个异常没有被处理。这看起来不正确。
因此，这个问题：应该怎么做？
阿波罗服务器堆栈跟踪，在情况下，它可以帮助：
