Currently when running this, I get an error saying that lineItems is not defined. How can I get the console.log to work here?

My Code:

await stripe.checkout.sessions.listLineItems(
      session.id,
      { limit: 5 },
      function lineItems(err, lineItems) {
        if (err) {
          console.log(err);
        } else {
          var price = lineItems.data[0].price.id;
        }
        return price;
      }
    );

    const priceId = lineItems();

    // console log price from line items
    console.log(priceId);

Any help is appreciated, thanks!
