I'm trying to send request using `Postman` to test `Klarna` payment, According to this [API DOC](https://developers.klarna.com/api/#checkout-api-create-a-new-order), We use `POST /checkout/v3/orders` to send a request so that we can create order (For the testing environment they use `https://api.playground.klarna.com/` + rest of url), But when i'm trying to send the given example in the above link(on the right side), It says that

```
{ "error_code" : "BAD_VALUE", "error_messages" : [ "Bad value: order_tax_amount" ], "correlation_id" : "12255531-ffcb-4a91-a375-04577fca78e5" }

```

When i read what does it require in the [documentation](https://developers.klarna.com/api/#checkout-api__create-a-new-order__order_lines__total_tax_amount), It says that the value should be formatted in some formula `±1 of total_amount - total_amount * 10000 / (10000 + tax_rate)`, When i calculate that the result `4545.4545` when i change the value in the request and try again, It gives the same error.
Can anybody help me with that?
Thanks
