【问题描述】:
我在部署功能时很好,但后来它停止工作,我不知道为什么。我已经恢复到示例代码(from here 或 here):
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
// Listens for new messages added to /messages/:pushId/original and creates an
// uppercase version of the message to /messages/:pushId/uppercase
exports.makeUppercase = functions.database.ref('/messages/{pushId}/original')
.onWrite(event => {
// Grab the current value of what was written to the Realtime Database.
const original = event.data.val();
console.log('Uppercasing', event.params.pushId, original);
const uppercase = original.toUpperCase();
// You must return a Promise when performing asynchronous tasks inside a Functions such as
// writing to the Firebase Realtime Database.
// Setting an "uppercase" sibling in the Realtime Database returns a Promise.
return event.data.ref.parent.child('uppercase').set(uppercase);
});
但是现在,当我运行 firebase deploy --only functions 时,我得到:
=== Deploying to 'mydb'...
i deploying functions
i functions: ensuring necessary APIs are enabled...
i runtimeconfig: ensuring necessary APIs are enabled...
+ runtimeconfig: all necessary APIs are enabled
+ functions: all necessary APIs are enabled
i functions: preparing functions directory for uploading...
i functions: packaged functions (2.04 KB) for uploading
! functions: Upload Error: Cannot read property 'response' of undefined
i starting release process (may take several minutes)...
i functions: updating function makeUppercase...
! functions[makeUppercase]: Deploy Error: Function load error: Node.js module defined by file index.js is expected to export function named makeUppercase
+ functions: 0 function(s) deployed successfully.
Functions deploy had errors. To continue deploying other features (such as database), run:
firebase deploy --except functions
Error: Functions did not deploy properly.
怎么了?
控制台显示相同的错误消息,没有更多解释:
【问题讨论】:
-
请显示部署命令的输出,将 --debug 添加到命令行参数。
-
带有 --debug 的部署命令的输出太大了,无法放在这里...如果您认为它可能有帮助,我可以捕获它并通过电子邮件发送给您。我复习了一下,并没有学到很多东西。
-
@frank-van-puffelen 我看到你添加了一个“google-cloud-functions”标签。这不是和 Firebase 函数完全不同吗?
-
Cloud Functions for Firebase 是 Google Cloud Functions,但添加了集成 Firebase 功能的附加功能。您可以将您的日志发送到 pastebin 之类的服务并在此处链接。
