GraphQL Does Not Reflect Catalog Rule Discounts

[tuyennn]

Preconditions and environment

• Magento version: 2.3.x to 2.4.x

Steps to reproduce

1. A product match a catalog rule
2. Below is the indexed price of a sample product: sku: FOO

customer_group_id	price	final_price	min_price	max_price
0	275.000000	247.000000	247.000000	247.000000
1	275.000000	247.000000	247.000000	247.000000
2	275.000000	247.000000	247.000000	247.000000

3. Query with a graphql

{
  products(
    filter: { sku: { eq: "FOO" } }
    pageSize: 1
    currentPage: 1
  ) {
    total_count
    page_info {
      page_size
      current_page
    }
    items {
      id
      name
      sku
      price_range {
        minimum_price {
          regular_price {
            value
            currency
          }
          final_price {
            value
            currency
          }
          discount {
            amount_off
            percent_off
          }
        }
        maximum_price {
          regular_price {
            value
            currency
          }
          final_price {
            value
            currency
          }
          discount {
            amount_off
            percent_off
          }
        }
      }
    }
  }
}

4. Observe the response with NOT logged in customer
5. Observe the response with LOGGED in customer and compare to step 4th

Expected result

Response of the price_range from graphql for both scenarios

{
    "data": {
        "products": {
            "total_count": 1,
            "page_info": {
                "page_size": 1,
                "current_page": 1
            },
            "items": [
                {
                    "id": 1,
                    "name": "FOO",
                    "sku": "FOO",
                    "price_range": {
                        "minimum_price": {
                            "regular_price": {
                                "value": 275,
                                "currency": "USD"
                            },
                            "final_price": {
                                "value": 247,
                                "currency": "USD"
                            },
                            "discount": {
                                "amount_off": 28,
                                "percent_off": 10.18
                            }
                        },
                        "maximum_price": {
                            "regular_price": {
                                "value": 275,
                                "currency": "USD"
                            },
                            "final_price": {
                                "value": 247,
                                "currency": "USD"
                            },
                            "discount": {
                                "amount_off": 28,
                                "percent_off": 10.18
                            }
                        }
                    }
                }
            ]
        }
    }
}

Actual result

Response for guest customer is ok, but for the logged in customer the response was wrong and doesn't reflect the catalog rule:

{
    "data": {
        "products": {
            "total_count": 1,
            "page_info": {
                "page_size": 1,
                "current_page": 1
            },
            "items": [
                {
                    "id": 1,
                    "name": "FOO",
                    "sku": "FOO",
                    "price_range": {
                        "minimum_price": {
                            "regular_price": {
                                "value": 275,
                                "currency": "USD"
                            },
                            "final_price": {
                                "value": 275,
                                "currency": "USD"
                            },
                            "discount": {
                                "amount_off": 0,
                                "percent_off": 0
                            }
                        },
                        "maximum_price": {
                            "regular_price": {
                                "value": 275,
                                "currency": "USD"
                            },
                            "final_price": {
                                "value": 275,
                                "currency": "USD"
                            },
                            "discount": {
                                "amount_off": 0,
                                "percent_off": 0
                            }
                        }
                    }
                }
            ]
        }
    }
}

Hi @tuyennn,

Thanks for your reporting and collaboration.

We have tried to reproduce the issue in Latest 2.4-develop instance and we are not able to reproduce the issue.Kindly refer the screenshots.

Response for Guest Customer

Response for LOGGED in customer

Both are reflecting catalog rule discounts.

Kindly recheck the issue in Latest 2.4-develop instance and elaborate the steps to reproduce if the issue is still reproducible.

Thanks.
