Hello 👋
PaymentIntents API doesn't support line items

Line items are only supported by Checkout, Payment Links, Invoicing API

Thanks for the reply. And in this case, how can I implement payment with an already saved card? Maybe there is some best practice? Via Invoicing?

Yes, you could create a one-off invoice using invoicing APIs where for line items, you'd create invoice items

https://stripe.com/docs/invoicing/integration

instead of using send_invoice collection method, you can set it to charge_automatically

That way, once the invoice is finalized it will attempt to charge the payment method that you either pass in as default_payment_method
https://stripe.com/docs/api/invoices/create?lang=node#create_invoice-default_payment_method

or you set under customer.invoice_settings.default_payment_method
