@naxiaoguang 时间太久了，不好意思，一直没有时间
今天测试了下

环境

• run-rs 4.2.0
• Windows10
• Node 12.14.0

代码

const mongoose = require('mongoose')
const Acid = require('mongoose-acid')
const os = require('os')
const hostname = os.hostname()

mongoose.set('debug', false)
Acid.set('debug', false)

const uri = os.platform() === 'win32' ? `mongodb://${hostname}:27017,${hostname}:27018,${hostname}:27019/test` : 'mongodb://localhost:27017,localhost:27018,localhost:27019/test'
let conn

const Account = mongoose.model('Account', new mongoose.Schema({
    balance: Number
}))
const People = mongoose.model('People', new mongoose.Schema({
    name: String,
    balance: Number
}))

async function test() {
    let conn = await mongoose.connect(uri, {
        replicaSet: 'rs',
        useUnifiedTopology: true,
        useNewUrlParser: true
    })

    // await new Account({ balance: 300 }).save()

    await Acid(async (session) => {
        let account = await Account.findOne({ _id: '5e1438aef13bc455b07bf22d' }).session(session)
        account.balance += 300
        await account.save()
        await new People({ balance: account.balance }).save({ session })
        throw new Error('THROW ERROR')
    })

    await conn.disconnect()
}
test()

并没有发现你出现的问题，你的问题应该和这个库没有关系，应该是你mongodb连接的配置问题？

看下这些副本集连接的配置，确定下您的问题吧
