回测时 query_all_level_finance_options 无法获取到合约数据

如下代码：

tq_api = tqsdk.TqApi(
        auth=tqsdk.TqAuth(username, password),
        backtest=tqsdk.TqBacktest(
            start_dt=date(2026, 1, 1),
            end_dt=date(2026, 1, 9)
        )
    )
    klines = tq_api.get_kline_serial(
        symbol='SSE.510500',
        duration_seconds=86400,
        data_length=2,
    )
     try:
        while True:
            tq_api.wait_update()
            if tq_api.is_changing(klines) and klines.iloc[-1]['volume'] != 0:
                 pre_kline = klines.iloc[-2]
                last_kline = klines.iloc[-1]
                last_kline_dt = datetime.fromtimestamp(last_kline['datetime']/1e9)
                 instrument_date = last_kline_dt.date()
                base_price = pre_kline['close']
                underlying_symbol = 'SSE.510500'
                 itm_symbols, atm_symbols, otm_symbols = tq_api.query_all_level_finance_options(
                    underlying_symbol,
                    base_price,
                    'CALL',
                    nearbys=0,
                    has_A=False,
                )
                 print(f'{instrument_date=}')
                print(f'{base_price=}')
                print(f'{itm_symbols=}')
                print(f'{atm_symbols=}')
                print(f'{otm_symbols=}')
     except tqsdk.BacktestFinished as e:
        print('Backtest Finished...')
    finally:
        tq_api.close()

输出的结果如下，都无法获取到合约列表：
