下面是我架构文件

import * as mongoose from 'mongoose';
import {HydratedDocument} from 'mongoose'
export type MemberDocument=HydratedDocument<memberAddress>;
@Schema()
export class memberAddress{
    @Prop()
    memver_id:string
   
    @Prop()
    city_id:string
    @Prop()
    state_id:string

    @Prop()
    pincode:number
    @Prop()
    address:string
    }
export const memberAddressSchema= SchemaFactory.createForClass(memberAddress)

但我还是很困惑我到底卡在哪里了？？？？ObjectParameterError：Document（）的参数“obj”必须是一个对象，已将类成员Dto { }
