Firebase Firestore onSnapshot PayloadToolargeError：Expo/React本机项目上的请求实体太大

Question

我有Expo/React本机项目订阅listen Firestore集合更新。我将Expo SDK从39更新到40，当调用时，onSnapshot回调函数开始抛出'PayloadToolArgeError：request entity too large'。我没有更新集合中的文档，也没有更改代码。Firebase版本是，“Firebase”：“7.9.0”，我在升级Expo SDK时没有更新它。

有没有人知道这是什么原因造成的，如何修复？

  componentDidMount = () => {

//Subscribe for collection changes
const unSubscribeUpdates = this.unsubscribe = db.collection("test_collection")
.onSnapshot({includeMetadataChanges: false}, this.onTestCollectionChanged).bind(this);
 
//Subscribe for favourite changes
const unSubscribeFavouriteUpdates = this.unsubscribe = db.collection("favourites")
.doc(Firebase.auth().currentUser.uid)
.onSnapshot({includeMetadataChanges: false},this.onFavouritesChanged).bind(this);

this.setState({ collection_items: items, favourites:favourites, unSubscribeUpdates: unSubscribeUpdates, unSubscribeFavouriteUpdates:unSubscribeFavouriteUpdates });

而听众是这样的

  onFavouritesListChanged = (doc) => {
    console.log("onFavouritesListChanged for user :" + Firebase.auth().currentUser.uid);
.....

  onVideoListChanged = (snapshot) => {
    console.log("onVideoListChanged");
    console.log("videos length " + this.state.videos.length);

这就是错误所在

OnVideoListChanged
PayloadToolArgeError：readStream(/users/nnn/.nvm/versions/node/v14.15.4/lib/node_modules/expo-cli/node_modules/@expo/dev-server/node_modules/raw-body/index.js:155:17)处的请求实体太大，getRawBody(/users/nnn/.nvm/versions/node/v14.15.4/lib/node_modules/raw-body/index.js:108:12)处tic/index.js:75:16)在调用时(/users/nnn/.nvm/versions/node/v14.15.4/lib/node_modules/expo-cli/node_modules/connect/index.js:239:7)在下一个(/users/nnn/.nvm/versions/node/v14.15.4/lib/node_modules/expo-cli/node_modules/connect/index.js:183:5)在调用时

结果表明，在Expo中没有出现这种情况，而是在NodeJS14中将太长的字符串打印到console.log输出中时出现这种情况。
