hasManyDeep with 4 level doesn't work

[bhattji]

I am trying to access the 4th table, but it gives errors cities.city_id doesn't exists. but why should it look for city_id in cities table? it should look for id

//hasManyDeeo
    public function asset_depreciations()
    {
        return $this->hasManyDeep(AssetDepreciation::class, [City::class, Location::class, Asset::class]);
    }

Hi @bhattji, Please share the migrations of all tables involved in this relationship. In which model is the asset_depreciations relationship defined?
