我的脚本一直在引发这个错误，我写的代码是为了测试Firestore的安全规则。我写的代码是为了测试Firestore的安全规则，我基本上想测试我的Firestore的安全性，同时添加javascript功能。它是可以写在firestore控制台的规则，并保存它们，然后和那里，但我想使用IDE - VS代码。
我想知道如何解决 "FIRESTORE (7.14.3) INTERNAL ASSERTION FAILED: value must be undefined or Uint8Array"。 我更新了我的npm，也尝试了一个我在Github上找到的答案，它说让我先安装 "npm i jest-environment-uint8array"。但没有成功。我也试过使用 "TextEncoder"，比如： var uint8array = new TextEncoder("utf-8").encode("Posts"); var string = new TextDecoder("utf-8").decode(uint8array);这也不行。如果你们能彻底回答我，我会非常感激，因为我只是个新手。
我的测试代码是
const { setup, teardown } = require("./helpers");
describe("General Safety Rules", () => {
afterEach(async () => {
await teardown();
});
test("should deny a read to the posts collection", async () => {
const db = await setup();
const postsRef = db.collection("Posts");
await expect(postsRef.get()).toDeny();
});
});
我的helper js基本都有设置，当我的代码完成后的拆解。
const firebase = require("@firebase/testing");
const fs = require("fs");
module.exports.setup = async (auth, data) => {
const projectId = `rules-spec-${Date.now()}`;
const app = firebase.initializeTestApp({
projectId,
auth
});
const db = app.firestore();
// Apply the test rules so we can write documents
await firebase.loadFirestoreRules({
projectId,
rules: fs.readFileSync("firestore-test.rules", "utf8")
});
// write mock documents if any
if (data) {
for (const key in data) {
const ref = db.doc(key); // This means the key should point directly to a document
await ref.set(data[key]);
}
}
// Apply the actual rules for the project
await firebase.loadFirestoreRules({
projectId,
rules: fs.readFileSync("firestore.rules", "utf8")
});
return db;
};
module.exports.teardown = async () => {
// Delete all apps currently running in the firebase simulated environment
Promise.all(firebase.apps().map(app => app.delete()));
};
错误是

这似乎是一个兼容性问题之间的最新的 @firebase/[email protected] 版本和内部使用的 [email protected] 版本。我也遇到了同样的错误，用临时的变通方法解决了。
试着降级你的 @firebase/testing 版本为 ^0.15.0 经过快速的 npm i 它为我工作。你仍然可以升级到最新版本以后，只要他们修复当前的兼容性问题。
一旦发生这种情况，我会尽快更新我的答案。
更新了。这是我在 firebase-js-sdk GitHub 页面上创建的问题。https:/github.comfirebasefirebase-js-sdkissues3096。.
似乎与测试框架Jest中的一个bug有关。这个问题描述了一个不需要降级的解决方法。
一旦不需要这个解决方法了，我会尽快更新我的回答。
这是Firebase的问题。
显然，这是Jest中的一个bug造成的......
... 包括这个变通方法。
重现和修复步骤 ...
