                                    $expr: {
                                        $in: ["$_id", '$$proList']
                                    }
                                }
                            }
                        ],
                        as: 'cart Items' //converted as cart Items name
                    }
                }

            ]).`to array`()
            resolve(`cart Items`)
        })
    }

db. cart. aggregate().to Array is not a function I tried to remove the to array but it shows as un defined

Issue is you're doing toArray() on promise, it should be something like this.. you don't need to create custom promise..

const getCartItems = () => {
  // ...
  const items = await db.cart.aggregate([...])
  return items.toArray();
  ...
}
