Show product price via shopify API. does not appear

Hey guys, can you give me a quick little help?

I’m pulling products via shopify API.
(List Shopify products)

Everything is working “List products”, this part, repeater group > image, texts…

But when creating the price, it does not appear in the list to select

Also in “Register Product” post method, the shopify code gives error when saving.

But the “Price” can not save

Can you help me?
