Stripe plugin payment error

Hello,

Since Paypal charges are very high per transaction vs Stripes almost 1%+ less than Paypal.

I followed the api guide and instructions but still this message below shows on the payment page;
You cannot use line_items.amount, line_items.currency, line_items.name, line_items.description, or line_items.images in this API version. Please use line_items.price or line_items.price_data. Please see https://stripe.com/docs/payments/checkout/migrating-prices for more information.
