Getting Error status code 405 while Sending PATCH request for updating in app purchases

Hi I am getting error status code 405 while sending PATCH request for updating in app purchases with using appstore connect rest api. However I can create an in app purchase with rest api but I cant localize and update them. I tried with scopes in JWT and without scopes in JWT but result is same. Can you help me about that?

Also I tried to create more than one in app purchase with a payload like that:

{
  "data": [{
    "type": "inAppPurchases",
    "attributes": {
      "name": "dummy-353535",
      "productId": "DUMMY353535",
      "inAppPurchaseType": "CONSUMABLE",
      "reviewNote": "TEST",
      "availableInAllTerritories": true
    },
    "relationships": {
      "app": {
        "data": {
          "type": "apps",
          "id": "<APP ID>" 
        }
      }
    }
  },
  {
    "type": "inAppPurchases",
    "attributes": {
      "name": "dummy-663435",
      "productId": "dummy663435",
      "inAppPurchaseType": "CONSUMABLE",
      "reviewNote": "Trying to create more than one dummy",
      "availableInAllTerritories": true
    },
    "relationships": {
      "app": {
        "data": {
          "type": "apps",
          "id": "<APP ID>"
        }
      }
    }
  }]
}

but I get an error like that:

{
    "errors": [
        {
            "id": "ffc324af-1a66-4ea8-a086-ba41ee7069de",
            "status": "422",
            "code": "ENTITY_UNPROCESSABLE",
            "title": "The request entity is not a valid request document object",
            "detail": "Unexpected or invalid value at 'data'.",
            "meta": {
                "position": {
                    "row": 2,
                    "column": 11
                }
            }
        }
    ]
}

Can you help me about that too? I am sending requests with postman by the way
