node.js - 方法 "collection.find()"最多接受两个参数

Question

const roomSchema = new mongoose.Schema({
    roomname: {
        type: String,
        required: true
    },
    users: {
        type: Array,
        required: true
    },
    createdDate: {
       type: Date,
       default: new Date()
    },
    admins: {
        type: Array
    },
    groupType: {
        type: String,
        required: true
    },
    requests: {
        type:Array
    },
    ip: {
        type:String,
        required:true
    },
    country:{
        type:String,
        required:true
    }
});
const roomModel=mongoose.model('room',roomSchema)
const getUsersInaRoom=async ()=>{
    const res = await roomModel.find({ 'roomname': 'room1' });
    console.log(res);
}
getUsersInaRoom();

它抛出的错误是:

node:6123) UnhandledPromiseRejectionWarning: MongoInvalidArgumentError: Method "collection.find()" accepts at most two argumentsat Collection.find (/Users/macpro/Desktop/React/chat-using-socket/backend/node_modules/mongodb/lib/collection.js:238:19)

几分钟前它还可以完美运行，现在抛出上述错误。

新版本的 mongoose 似乎有问题。运行 npm rm mongoose 卸载当前版本，运行 npm i mongoose@5.13.8 安装之前的版本并重试。
