Getting a missing argument error in _parse_broker_order

This error comes up when I’m making a bracketing order:

File “C:\Users\That Guy\PycharmProjects\allpacaTest\venv\lib\site-packages\lumibot\brokers\”, line 302, in _flatten_order
sub_order = self._parse_broker_order(json_sub_order, strategy_name)
TypeError: _parse_broker_order() missing 1 required positional argument: ‘strategy_object’

Parsing the code, it doesn’t look like it could ever work:

def _flatten_order(self, order):
    """Some submitted orders may trigger other orders.
    _flatten_order returns a list containing the main order
    and all the derived ones"""
    orders = [order]
    if order._raw.legs:
        strategy_name = order.strategy
        for json_sub_order in order._raw.legs:
            sub_order = self._parse_broker_order(json_sub_order, strategy_name)

    return orders

def _parse_broker_order(self, response, strategy_name, strategy_object):

Is this a bug or am I just missing something?

Thanks for your help.
