Update Stop Loss on a filled order

hi there, I am trying to update the stop loss after knowing the price at which a order was filled. So I call list_positions to get the fill price and calculate a stop loss to update. I call

order = api.replace_order(order_id=“97d0953b-5bbc-4a3f-8c39-241cd8a5d014”,
stop_price=208.90
)
BUt i get an error saying,

alpaca_trade_api.rest.APIError: only simple orders can be replaced at this time

Is it not possible to update stop_price?

Did you ever get an answer or figure this out? I don’t see how, so I am cancelling the original and creating a new order. But there is no documentation on how to create a ‘simple’ order with a stop_loss, so I’m wondering if you found it?
