我正在尝试在Firebase云函数中运行以下代码。我尝试做的是遍历名为 savedData 的 Firestore 集合中的所有文档,解析存储在每个文档中的字符串的 JSON,然后将解析后的数据存储到名为 stgPicks 的集合中的新文档中。保存的数据收集集合中的每个文档应在 stgPicks 集合中创建 50-100 个新文档。当我尝试运行该函数时,我得到以下错误代码。任何人都可以帮助调试此代码吗?我不确定我是否正确处理了批处理。Error: 3 INVALID_ARGUMENT: maximum 500 writes allowed per request at Object.callErrorFromStatus (/workspace/node_modules/@grpc/grpc-js/build/src/call.js:30:26) at Object.onReceiveStatus (/workspace/node_modules/@grpc/grpc-js/build/src/client.js:175:52) at Object.onReceiveStatus (/workspace/node_modules/@grpc/grpc-js/build/src/client-interceptors.js:341:141) at Object.onReceiveStatus (/workspace/node_modules/@grpc/grpc-js/build/src/client-interceptors.js:304:181) at Http2CallStream.outputStatus (/workspace/node_modules/@grpc/grpc-js/build/src/call-stream.js:115:74) at Http2CallStream.maybeOutputStatus (/workspace/node_modules/@grpc/grpc-js/build/src/call-stream.js:154:22) at Http2CallStream.endCall (/workspace/node_modules/@grpc/grpc-js/build/src/call-stream.js:140:18) at Http2CallStream.handleTrailers (/workspace/node_modules/@grpc/grpc-js/build/src/call-stream.js:265:14) at ClientHttp2Stream.emit (events.js:198:13) at ClientHttp2Stream.EventEmitter.emit (domain.js:466:23)exports.parsePicksRecover = functions.https.onRequest((req, res) => { let savedDataRef = admin.firestore().collection('savedData') let allDrafts = savedDataRef .get() .then((snapshot) => { snapshot.forEach((doc) => { const docId = doc.id const getDoc = admin .firestore() .collection('savedData') .doc(`${docId}`) .get() .then((doc) => { if (!doc.exists) { console.log('No matching document.') }

我确实在使用PHP SDK时遇到了相同的错误,在我的情况下,问题是在提交之后,我需要创建一个新的实例,我认为它会尝试提交旧文档更改两次,这就是为什么你遇到每个请求允许的最大500次写入错误,例如:batch
let batch = admin.firestore().batch();
for (i = 1; i <= 10000; ++i) {
// do something with the batch
if (0 === i % 500) {
batch.commit();
batch = admin.firestore().batch();
}
}
batch.commit();
