Mongo Tailable Cursor {错误:尾部游标中没有更多文档}

Question

当我尝试运行我的代码时，它显示"MongoError: No More Documents in Tailed“。

const mongoose = require('mongoose');
const Schema = require('mongoose').Schema;
const dataSchema = new Schema({
    id: String,
    name: Number,
    timestamp: Number
}, { capped: 5000000 });
const CappedData = mongoose.model('cappedData', dataSchema);
const dataCursor = CappedData.find({}).tailable(true, {awaitData: true}).cursor();
dataCursor.on('data', doc => {
    console.log(data);
});

Answer 1

在空的上限集合上调用Tailable将导致此错误，请确保该集合不为空(已对其进行测试并正常工作)
