Discount Code Lookup API not working for Buy X Get Y

[Enea]

Hi,

I am trying to use this API endpoint: https://shopify.dev/docs/admin-api/rest/reference/discounts/discountcode#lookup-2020-01

It does not work when trying to look up a code that is a "Buy X get Y" when the customer spend is set to "Minimum purchase amount" it does oddly work when the customer spend is set to "Minimum quantity of items"

[Enea]

I am also trying to use GraphQL to do it but I am getting this error:

Field 'codeDiscountNodeByCode' doesn't exist on type 'QueryRoot'

With this query:

{
	codeDiscountNodeByCode(code: "SOME_CODE") {
    edges {
				node {
          id
        }
    }
  }
}
