When I create a Checkout session, I am creating prices on the fly with price_data and product_data properties. For each item, I am putting metadata in the product_data.metadata property.
After payment is successfully finished, I fetch the session data in order to display Payment Successful page to the customer. But for some reason, metadata of the items are empty. Metadata of the items are present when I check it in the Dashboard, but they are empty when I fetch it with API.
I tried to fetch whole session data with expanded line_items property:
const session = await stripe.checkout.sessions.retrieve(session_id, { expand: ['line_items'] });
And I also tried to fetch the items directly:
const line_items = await stripe.checkout.sessions.listLineItems(session_id);
In both scenarios, metadata of each item is empty.

Method 1
When creating the items on the fly, metadata ends up in the product property, and not in the price property.
So I solved the issue with expanding the items with product data:
const line_items = await stripe.checkout.sessions.listLineItems(session_id, {
expand: ['data.price.product'],
});
The response have the metadata inside product property.
