Error with return from canceling an order already filled

[lvca]

Hi guys,

If I execute this:

curl -X DELETE "https://api.alpaca.markets/v2/orders/XXXXXXXXXXXXXX" -H "Authorization: Bearer YYYYYYYY"

I got HTTP 204 (OK) even if the order was already filled.

If you see the docs under https://alpaca.markets/docs/api-documentation/api-v2/orders/:

Cancel an order
DELETE/v2/orders/{order_id}
Attempts to cancel an open order. If the order is no longer cancelable (example: status="filled"), the server will respond with status 422, and reject the request. Upon acceptance of the cancel request, it returns status 204.

So I was expecting a 422 or anything different from 204 because the order has been filled.
