Encounter very weird problem with loopback4 (model wasn't really working well)

Question

For some unknown reason this.toEntities return my object to undefined

I dig few more and found out that return new this.entityClass(model.toObject()) return all data to undefined. Please have a look at the console area.

im running loobpack with this command line lb-tsc --copy-resources && tsc-watch --target ESNext --outDir ./dist --onSuccess "node --inspect ."

this is my packages version

macOS: Sonoma 14.1
node: 16.20.2

I ran few more test like below

 console.log(
      await this.emissionRepository.count(),
      await this.emissionRepository.find(),
      await this.plantActualDetailRepository.execute(`SELECT * FROM User`)
)

So if my understanding correctly my model is the one that doesn't really work well?. Since vanilla sql works perfectly.

import { Entity, model, property } from '@loopback/repository'

@model()
export class Emission extends Entity {
  @property({
    type: 'number',
    id: true,
    generated: true,
  })
  id?: number

  @property({ type: 'number' })
  no_of_year: number

  @property({ type: 'number' })
  co2_actual_emission: number

  @property({ type: 'number' })
  emissionId?: number

  constructor(data?: Partial<Emission>) {
    super(data)
  }
}

export interface EmissionRelations {
  // describe navigational properties here
}

export type EmissionWithRelations = Emission & EmissionRelations

Just found the answer by changing to this command lind (--target 2021)

   $ lb-tsc --copy-resources && tsc-watch --target es2021 --outDir ./dist --onSuccess \"node .\"

And i can confirm that using es2022 will result in undefined model as stated above
