Different Results GraphiQL vs Postman vs Python Request

[max15characters]

I don't know what label should I choose for this, so please forgive me.

I encountered a really bizarre problem, where API request results differ between GraphiQL, Postman and via Python Request.

Request:

{
  product(id: "gid://shopify/Product/7161071599788") {
    variants(first: 10) {
      edges {
        node {
          unitPriceMeasurement {
            quantityValue
          }
        }
      }
    }
  }
}

GraphiQL result (this is what I'm after):

{
  "data": {
    "product": {
      "variants": {
        "edges": [
          {
            "node": {
              "unitPriceMeasurement": {
                "quantityValue": 1.44
              }
            }
          }
        ]
      }
    }
  },
  "extensions": {
    "cost": {
      "requestedQueryCost": 11,
      "actualQueryCost": 5,
      "throttleStatus": {
        "maximumAvailable": 4000,
        "currentlyAvailable": 3995,
        "restoreRate": 200
      }
    }
  }
}

Postman result:

{
    "errors": [
        {
            "message": "Field 'unitPriceMeasurement' doesn't exist on type 'ProductVariant'",
            "locations": [
                {
                    "line": 11,
                    "column": 21
                }
            ],
            "path": [
                "query",
                "product",
                "variants",
                "edges",
                "node",
                "unitPriceMeasurement"
            ],
            "extensions": {
                "code": "undefinedField",
                "typeName": "ProductVariant",
                "fieldName": "unitPriceMeasurement"
            }
        }
    ]
}

Python Response result:

{
  'data': {
    'product': None
  }
}

All using the same API version and token.

I'm not too worried about Postman, but in Python this only happen with 2 products (what I've tested so far).

Can anyone enlighten me?

Hi @max15characters 

Please check if the version of the API used for GraphiQL vs Postman vs Python Request is consistent.

Thanks Kyle, while that wasn't the issue, I tried sending the request using admin API 2024-10 instead of storefront API and now it works everywhere.

It's been working well with storefront API since March, and it only started spitting issues just now. Maybe it was deprecated?
