Conditional Order Rejected: No Reason Given

[kasahh]

I am trying to send in a conditional market order using websocket. The order is sent successfully and you can even see it from the Bybit testnet dashboard but sometimes the order disappears after sometime and when I check the order history, it says it was rejected but it doesn't give a reason why it was rejected.

This is what the order message I sent via websocket looks like:

{'header': {'X-BAPI-TIMESTAMP': '1722885966243', 'X-BAPI-RECV-WINDOW': '8000'}, 'op': 'order.create', 'args': [{'category': 'linear', 'orderType': 'Market', 'positionIdx': 1, 'price': '0.28928', 'qty': '353.0', 'side': 'Buy', 'symbol': 'PONKEUSDT', 'triggerPrice': '0.28928', 'triggerBy': 'MarkPrice', 'triggerDirection': 1, 'reduceOnly': False, 'closeOnTrigger': False}]}

Thanks in advance.
