When I try to creating an order through shopify API always return an empty order list

[EDO3]

When I call the admin/api/2024-01/orders.json to create an order, it always returns a response with 200 status and an empty order list. 

Request:

{

    "order": {

        "email": "vendorsupport@xxx.com",

        "inventory_behaviour": "decrement_obeying_policy",

        "line_items": [{

            "variant_id": "46924554109270",

            "price": 473.33,

            "quantity": 1

        }],

        "test": false,

        "shipping_address": {

            "first_name": "xxxxxx",

            "last_name": "xxxxx",

            "address1": "xxxxx",

            "city": "xxxxx",

            "country": "xxxxxx",

            "province": " ",

            "zip": "3000",

            "phone": " "

        },

        "billing_address": {

            "first_name": "xxxxxx",

            "last_name": "xxxxxx",

            "address1": "xxxxxxxx",

            "city": "xxxxxxxx",

            "country": "xxxxxxxxx",

            "province": " ",

            "zip": "3000",

            "phone": " "

        },

        "customer": {

            "first_name": "xxxxxxxxx",

            "last_name": "xxxxxxxx",

            "email": "vendorsupport@xxx.com"

        },

        "name": "6727"

    }

}

Response:

{

    "orders": []

}

Anyone know what's wrong with this? 

Thanks for your help.
