函数崩溃，没有异常跟踪`Error：无法使用Google Cloud函数处理请求`

Question

我看到这是堆栈驱动程序日志：

2018-11-15 08:37:10.917 WET
function-1
x8256v6gdjvi
Function execution started

2018-11-15 08:37:13.081 WET
function-1
x8256v6gdjvi
Function execution took 2164 ms, finished with status: 'crash'

webhook触发器的响应是带有Error: could not handle the request的500

此错误的原因可能是什么？我该如何诊断？

它在本地工作正常...
