Function not functioning as expected in NestJS MongoDB unique field feature

I am trying to set the "unique:true" attribute for the name property in my NestJS - MongoDB schema, but it is not working as expected by default.

@Schema()
export class User {
  @Prop()
  userId:string;
  
  @Prop({ 
    type:String,
    required:true,
  })
  name:string;

  @Prop({ required: true})
  password:string;
  
  @Prop({ required: true })
  email:string;

  @Prop({default:"user"})
  role:string
}

This setup works fine for 'required' and 'default', however, the 'unique' field does not seem to be functioning properly.

Perhaps you intend to validate the input field by using the IsUnique method in this way:

import { Schema, Prop } from '@nestjs/mongoose';
import { IsUnique } from 'class-validator';


@Schema()
export class User {
  @Prop()
  userId:string;
  
  @Prop({ 
    type:String,
    required:true,
  })
  name:string;

  @Prop({ required: true})
  password:string;
  
  @Prop({ required: true })
  @IsUnique({ message: 'The field must be unique.' })
  email:string;

  @Prop({default:"user"})
  role:string
}
