Hello,

In my Odoo 18 POS, I want to customize the receipt so that:

• Only products of type "combo" are displayed.
• The individual items included in the combo are not listed separately.
• The displayed price is the total price of the combo, not the sum of the child products.
• The receipt layout remains the default Odoo POS layout.
• The order date should be displayed, not just the payment timestamp.

I have tried overriding OrderReceipt using a CustomOrderReceipt component, but I encounter errors such as OwlError or Cannot read properties of undefined when filtering lines or accessing paymentlines.

I am looking for an approach or working example to:

• Filter order lines to show only combos.
• Display the total price of the combo.
• Show the order date.
• Avoid Owl errors caused by missing data (e.g., payment_method undefined).

Any advice or working examples would be greatly appreciated.
