Ambiguous contract: Contract(secType='EVENT')

Altan Alpay All Messages By This Member #50948 Do you know what secType='EVENT' is for? I couldn't find any documentation in TWS API When I qualify for future options, I receive this message: Ambiguous contract: FuturesOption(symbol='NQ', lastTradeDateOrContractMonth='20230403', strike=12750.0, right='P', exchange='CME'), possibles are [Contract(secType='FOP', conId=618037607, symbol='NQ', lastTradeDateOrContractMonth='20230403', strike=12750.0, right='P', multiplier='20', exchange='CME', currency='USD', localSymbol='Q1AJ3 P12750', tradingClass='Q1A'), Contract(secType='EVENT', conId=623833192, symbol='NQ', lastTradeDateOrContractMonth='20230403', strike=12750.0, right='P', multiplier='1', exchange='CME', currency='USD', localSymbol='ECNQJ303 P1275', tradingClass='ECNQ')]
