Current behavior

Aliases in schemas don't work.

} `

Minimized Schema only for two fields:

` @Schema({ collection: 'accounts_slideshow' }) export class AccountSlideshow extends Document { @Prop({ alias: 'limit', type: Number}) limit2: number

//@Prop({ type: SchemaFactory.createForClass(Filter), ref: () => Filter }) // filter2: Filter

// @Prop({ type: [ArchitectureItemSchema] }) // architecture: ArchitectureItem[]

@Prop({ alias: 'position' }) position2: string } export type AccountSlideshowDocument = AccountSlideshow & Document

export const AccountSlideshowSchema = SchemaFactory.createForClass(AccountSlideshow) `

Repository:

` import { Injectable } from '@nestjs/common' import { InjectModel } from '@nestjs/mongoose' import { Model } from 'mongoose' import { AccountSlideshow, AccountSlideshowDocument, } from 'schemas/account.slideshow'

@Injectable() export class AccountSlideshowsRepository { constructor( @InjectModel(AccountSlideshow.name) private readonly _slideshowModel: Model, ) {}

public async find(): Promise { const res = this._slideshowModel.findOne() return await res.exec() } } `

Nestjs module: @Module({ imports: [ MongooseModule.forFeature([ { name: AccountSlideshow.name, schema: AccountSlideshowSchema }, ]), SequelizeModule.forFeature([Account, Item]), ], providers: [ AccountSlideshowsRepository, AccountsRepository, AccountSlideService, AccountHandler, ItemsRepository, ], controllers: [AccountSlideController], }) export class AccountSlideModule {}

Service

` @Injectable() export class AccountSlideService { constructor( private readonly _slidesRepository: AccountSlideshowsRepository, private readonly _accountHandler: AccountHandler, ) {}

public async getAccounts(offset: number): Promise { const settings = await this._slidesRepository.find() console.log(settings) // works and gets plain JavaScript object from Mongo db console.log(settings.limit2) - undefined console.log(settings.position2) - undefined } } `

I get data from Mongo db. There is not errors. But aliases don't work. I know, this is a bug.
