Creating OKEx orders using ccxt

Question

I'm trying to make program for creating SWAP orders in OKEx with StopLoss and TakeProfit in DEMO trading mode using ccxt module. But I got error: The current account mode does not support this API interface. How I can solve it, and is there some examples of creating orders? My attempt:

params = {
        'tdMode': 'isolated',
        'tpOrdPx': '-1',
        'slOrdPx': '-1',
        'tpTriggerPx': take_profit,
        'slTriggerPx': stop_loss,
        'headers': {
            'x-simulated-trading': '1'
        }

    }
order = exchange.create_order(
        f"XRP/USDT:USDT", 'market', 'buy', summa, price, params=params)

Error code:

File "/home/excl/.local/lib/python3.10/site-packages/ccxt/base/exchange.py", line 561, in throw_exactly_matched_exception
    raise exact[string](message)
ccxt.base.errors.AccountNotEnabled: okx {"code":"1","data":[{"clOrdId":"*id*","ordId":"","sCode":"51010","sMsg":"The current account mode does not support this API interface. ","tag":""}],"msg":"Operation failed."}

Solved by changing account mode from simple to portfolio mode. https://www.okx.com/academy/en/guide-to-portfolio-margin-mode-on-okex
