错误：发生了意外错误。 Firebase 函数

Question

我已将 firebase-functions 更新至 1.0.2 版，将 firebase-tools 更新至 3.18.4，将 firebase-admin 更新至 5.12.0

我正在上传一个生成缩略图的函数，该缩略图取自https://github.com/firebase/functions-samples/tree/master/quickstarts/thumbnails

[error] Error: An unexpected error has occurred.

Answer 1

你说过：

1. 您已将 firebase-functions 更新到版本 1.0.2
2. 代码是从 Cloud Function 示例中克隆出来的，没有任何更改

所以很可能您的问题来自 Cloud Functions V1.0.0 及更高版本已更改的事实，请参阅文档https://firebase.google.com/docs/functions/beta-v1-diff#storage

你应该改变

exports.generateThumbnail = functions.storage.object().onFinalize((object) => {

到

exports.generateThumbnail = functions.storage.object().onFinalize((object, context) => {

并根据文档根据对象相应地调整行。
