Erreur 500 with inAppPurchasePriceSchedules

Hello everyone,

I've been having some trouble with the App Store Connect API recently. Specifically, the price tiers have changed from 1,2,3,4 to 10000,10001,10002, etc. I modified my code accordingly and it worked fine for a while, but now I'm getting 500 errors.

I'm trying to make a POST request to the inAppPurchasePriceSchedules endpoint with the following JSON body:

POST https://api.appstoreconnect.apple.com/v1/inAppPurchasePriceSchedules

{
  "data": {
    "relationships": {
      "inAppPurchase": {

          "type": "inAppPurchases"
        }
      },
      "manualPrices": {
        "data": [
          {
            "id": "price_point_id_tiers_1000x",
            "type": "inAppPurchasePrices"
          }
        ]
      }
    },
    "type": "inAppPurchasePriceSchedules"
  },

    {
      "attributes": {

      },

            "type": "inAppPurchasePricePoints"
          }
        },

        }
      },
      "type": "inAppPurchasePrices"
    }
  ]
}
