There must be a Syntax Error in Phemex JSON: How do you make an order with a StopLoss and TakeProfit?

Question

def placeBUYStopLimitOrder(dollars, BTC_VALUE):
# boolean is on/off switch of client creation, False or True
client = Client(testnet_api_key, testnet_api_secret, True)

tid = "P_buy_100" + str(datetime.datetime.now())

# a 15% larger trigger
# print("BTC_VALUE: ", BTC_VALUE)
coreBTCValue = float(BTC_VALUE) * 10000
bullTriggerPrice = coreBTCValue * 1.15
bearTriggerPrice = coreBTCValue * 0.95

r = client.place_order(
{
    "clOrdID": tid,
    "symbol": "BTCUSD",
    "side": "Buy",
    "priceEp": coreBTCValue,
    "orderQty": dollars,
    "ordType": "Limit",
    "takeProfitEp": bullTriggerPrice,
    "tpTrigger": "ByLastPrice",
    "stopLossEp": bearTriggerPrice,
    "slTrigger": "ByMarkPrice"
})

This is a simple question with an elusive answer. Can anyone help by suggesting the correct JSON to send to the PHEMEX API?
