Current behavior

When using a unique key in the document schema,

@Schema()
export class User {
  @Prop({
    default: Math.random().toString().substr(2, 8),
  })
  handle: string;

  @Prop({ required: true, unique: true })
  display: string;
}

and if you try to create a model with a duplicate key, it ill crash the app
