Swagger plugin v4 not recognizing enum as a key in validated object

See original GitHub issue

Bug Report

Current behavior

I’ve updated my code to use swagger v4 with plugin, so it exposes DTO validations automatically. Everything work correctly, unless i use enum as a key of validated object. In output code, enum is not being imported and nest assumes it is global.

Input Code

import { IsBoolean, IsOptional } from 'class-validator';
import { ReservationReminderType } from '../../../shared/reservation/enums/reservation.reminder.type.enum';

export class UpdateShopNotifiactionsDto {
  @IsBoolean()
  @IsOptional()
  [ReservationReminderType.OneDayBefore]?: boolean;
}

Output Code (compiled)

const openapi = require("@nestjs/swagger");
const class_validator_1 = require("class-validator");
const reservation_reminder_type_enum_1 = require("../../../shared/reservation/enums/reservation.reminder.type.enum");

class UpdateShopNotifiactionsDto {
    static _OPENAPI_METADATA_FACTORY() {
        return { [ReservationReminderType.OneDayBefore]: { required: false, type: () => Boolean }, };
    }
}

Expected behavior

Output code should use reservation_reminder_type_enum_1 in its static _OPENAPI_METADATA_FACTORY() method.

Error
