Firebase云功能退出并显示代码16，什么是错误代码16，在哪里可以找到更多信息? [英] Firebase cloud function exits with code 16 what is error code 16 and where can I find more info?

问题描述

我在firebase上的一个云功能退出，错误代码为16.

one of my cloud functions on firebase exits with code 16 as an error.

我试图在google上找到该代码是什么，但根本没有运气.

I tried to google and find out what that code is but no luck at all.

Error: Process exited with code 16
    at process.on.code (/srv/node_modules/@google-cloud/functions-framework/build/src/invoker.js:393:29)
    at process.emit (events.js:189:13)
    at process.EventEmitter.emit (domain.js:441:20)
    at process.exit (internal/process/per_thread.js:168:15)
    at logAndSendError (/srv/node_modules/@google-cloud/functions-framework/build/src/invoker.js:184:9)
    at process.on.err (/srv/node_modules/@google-cloud/functions-framework/build/src/invoker.js:390:13)
    at process.emit (events.js:189:13)
    at process.EventEmitter.emit (domain.js:441:20)
    at emitPromiseRejectionWarnings (internal/process/promises.js:119:20)
    at process._tickCallback (internal/process/next_tick.js:69:34)

在哪里可以找到报告的错误代码，以便我理解为什么我的函数会退出?

Where can I find those error codes reported so I can understand why my function exits?

推荐答案

显然，经过调查，该错误表示类似Headers already sent的错误.

Apparently and after investigation, the error means something like: Headers already sent.

我在代码的某处有一个带标题的response.send()，然后，我又发送了另一个响应.

I had somewhere in my code a response.send() with headers and then, later on, I was sending another response.

如果Firebase团队可以详细说明这些问题并提供一些文档而不是蒙住我们的眼睛(根据我的理解)，那就太好了

Would be great if the Firebase team could elaborate with these issues and provide some documentation instead of leaving us blindfolded (to my understanding)
