When i push value to empty array it showing Node js

exports.OrderPlace = (req, res) => {
  const all_product = req.body.product_info;
  let meta = [];
  all_product.forEach((element) => {
    Ticket.find({ _id: element.product_id }, function (err, docs) {
      if (err) return handleError(err);
      if (docs[0]._id == element.product_id) {
        if (element.quantity < docs[0].quantity) {
          meta.push({
            cart_id: element.id,
            pro_id: element.product_id,
            quantity: element.quantity + " Asking quentity is not available!",
          });
        }
      }
    });
  });
  console.log(meta);
};

I’m trying to push cart_id , pro_id, quantity. its loging me empty value please help

Im expecting console.log(meta) values like

[
    {
        cart_id: "63db8665ba7126c2b35fb231",
        pro_id: "63d025a8eefcf49cdcdd5472",
        quantity: "36 Asking quentity is not available!",
    },
    {
        cart_id: "63dbc2a7fbf7daf48052189e",
        pro_id: "63ce4393c3433881173d1502",
        quantity: "40 Asking quentity is not available!",
    }
]

>Solution :

wrap the whole code block inside an async function, and use await inside the function to wait for the result of the Ticket.find operation.

exports.OrderPlace = async (req, res) => {
  const all_product = req.body.product_info;
  let meta = [];
  let flag = "";

  for (const element of all_product) {
    const docs = await Ticket.find({ _id: element.product_id }).exec();
    if (docs[0]._id == element.product_id) {
      if (element.quantity > docs[0].ticket_quantity) {
        flag = "false";
        meta.push({
          cart_id: element.id,
          pro_id: element.product_id,
          quantity: element.quantity + " Asking quentity is not available!",
        });
      }
    }
  }
  console.log({ flag: flag, meta });
};
