transactions.item_list.items Currency amount must be non-negative number in sandbox

[doers]

We can't submit payments with item_list in sandbox. Everything works fine without it.

Here is our payload:

{
  "transactions": [
    {
      "amount": { "total": "36.78", "currency": "SGD", "details": {} },
      "invoice_number": "f9d5a670-6f5e-4a92-84f2-416acf09b87c",
      "item_list": {
        "items": [
          {
            "sku": "",
            "name": "Item 2",
            "description": "A wonderful product",
            "quantity": "1",
            "price": "15.03",
            "currency": "SGD",
            "tax": "7%"
          },
          {
            "sku": "",
            "name": "Item 3",
            "description": "Another nice product",
            "quantity": "1",
            "price": "10.00",
            "currency": "SGD",
            "tax": "7%"
          }
        ],
        "shipping_address": {
          "recipient_name": "Test User",
          "line1": null,
          "line2": null,
          "city": null,
          "country_code": "SG",
          "postal_code": null,
          "phone": null,
          "state": null
        }
      }
    }
  ],
  "intent": "sale",
  "redirect_urls": {
    "return_url": "https://www.sandbox.paypal.com",
    "cancel_url": "https://www.sandbox.paypal.com"
  },
  "payer": { "payment_method": "paypal" }
}

And here is the response:

    "name": "VALIDATION_ERROR",
    "details": [
        {
            "field": "transactions.item_list.items",
            "issue": "Currency amount must be non-negative number, may optionally contain exactly 2 decimal places separated by '.', optional thousands separator ',', limited to 7 digits before the decimal point and currency which is a valid ISO Currency Code"
        }
    ],
    "message": "Invalid request - see details",

}
