Problem sending new orders to Kucoin

Description

This problem started ocurring around when Kucoin merged the HFT with the standard API. A lot of the times when sending a new order, CCXT returns a dictionary as if the order was correctly created, but consisting of mostly null values, except the orderID:

Example: {'info': {'orderId': '66b033cd693a4f0007d4e2f9'}, 'id': '66b033cd693a4f0007d4e2f9', 'clientOrderId': None, 'symbol': 'MTRG/USDT', 'type': None, 'timeInForce': None, 'postOnly': None, 'side': None, 'amount': None, 'price': None, 'stopPrice': None, 'triggerPrice': None, 'cost': None, 'filled': None, 'remaining': None, 'timestamp': None, 'datetime': None, 'fee': {'currency': None, 'cost': None}, 'status': None, 'lastTradeTimestamp': None, 'average': None, 'trades': [], 'fees': [{'currency': None, 'cost': None}], 'lastUpdateTimestamp': None, 'reduceOnly': None, 'takeProfitPrice': None, 'stopLossPrice': None}

The exception getting caught states "Order does not exist" when querying for that specific id (exchange.fetch_order)

This happens both with limit and market orders, with the amount verified via amount_to_precision and with enough funds, using exchange.create_order(pair,"market",side,amount)

Anybody else with this issue?

@nsanchez1980 Could you paste code snippet that we can reproduce this?

Just by creating a limit or market spot order using create_order is enough, the issue is sporadic: for example, now it works ok, but yesterday and up to a couple of hours it was almost impossible to create an order. Most likely is an issue on the Kucoin side, but why does ccxt returns an order ID with all null values? Wouldn't it be nice to return an error or an exception?

@nsanchez1980 Hello, returning only the orderId does not mean the order was not successful, many exchanges return only the OrderId upon placing an order.

For instance I just tested createOrder+fetchOrder and it worked

CCXT v4.3.73
kucoin.createOrder(LTC/USDT,market,buy,0.1)
{'amount': None,
 'average': None,
 'clientOrderId': None,
 'cost': None,

Yeah, fortunately now is running ok. What should I do when the error presents itself again? Any logs or something specific that could help pinpoint the issue?
