【问题描述】：
我正在尝试在本地测试我的云功能。我正在使用命令firebase functions:shell 成功启动模拟器。我的index.ts 中有以下云功能：
export const stripeCharge = functions.region('europe-west1').database
.ref('/payments/{userId}/{paymentId}')
.onWrite(async (change, context) => {
someCode;
});
我读到您应该通过以下方式调用 onWrite firestore 函数 (https://firebase.google.com/docs/functions/local-shell)：
stripeCharge({before: "oldData", after: "newData"})
但是，这会导致以下错误：
'Successfully invoked function.'

! Your function was killed because it raised an unhandled error.
错误发生在其他文件中，我不知道为什么。我错过了什么？
编辑：我的package.json：
{
"name": "functions",
"scripts": {
"lint": "tslint --project tsconfig.json",
"build": "tsc",
"serve": "npm run build && firebase serve --only functions",
"shell": "npm run build && firebase functions:shell",

【问题讨论】：
-
你使用的是哪个版本的节点？
-
@andresmijares 嗨，感谢您的帮助。
node --version打印8.16.0。有问题吗？ -
也许，您的函数在抱怨
context，在您的情况下，它触发了旧版本，尝试更新您的依赖项并确保您的 package.json，列出正确的节点版本 -
我要检查的最后一件事是，你在运行
firebase functions:shell之前运行npm run build吗？所以我们可以丢弃一个transpile问题 -
我也有同样的问题。使用 RTDB 时，我无法在本地运行函数。
