MDVA-37288: Wrong tier prices returned after GraphQL request

The MDVA-37288 quality patch for Adobe Commerce solves the issue where the wrong tier prices are returned after GraphQL request. This patch is available when the Quality Patches Tool (QPT) v.1.0.23 is installed. Please note that the issue is scheduled to be fixed in Adobe Commerce version 2.4.3.

Affected products and versions

• The patch was designed for Adobe Commerce on cloud infrastructure 2.4.2
• The patch is also compatible with Adobe Commerce on-premises and Adobe Commerce on cloud infrastructure 2.4.2

Issue

Steps to reproduce:

1. Add tier pricing to any item (for this example tier prices were added to items with id=1 and id=2).
2. Run GraphQL query with search that will include the items with tier prices and items without tier prices.

{
  products(pageSize: 20, currentPage: 1, search: "24-MB0") {
    items {
      id
      price_tiers {
        quantity
        final_price {
          value
        }
      }
    }
  }
}

Expected results:

Only items with tier prices should return proper tier prices:

{
  "data": {
        "products": {
            "items": [
                {
                    "id": 17,
                    "price_tiers": []
                },
                {
                    "id": 1,
                    "price_tiers": [
                        {
                            "quantity": 1,
                            "final_price": {
                                "value": 34
                            }
                        },
                        {
                            "quantity": 5,
                            "final_price": {
                                "value": 32
                            }
                        }
                    ]
                },
                {
                    "id": 23,
                    "price_tiers": []
                },
                {
                    "id": 19,
                    "price_tiers": []
                }
            ]
        }
    }
}

Actual results:

• All items coming after an item with tier pricing have tier pricing in the response.
• The tier pricing data that it’s returning is from the last item in the loop that had tier pricing.

response example:

{
    "data": {
        "products": {
            "items": [
                {
                    "id": 17,
                    "price_tiers": []
                },
                {
                    "id": 1,
                    "price_tiers": [
                        {

                        }

                            }
                        },
                        {
                            "quantity": 5,
