same problem for PBR-USD-STK.SMART

ib_insync seems to update interface 2 years ago https://github.com/erdewit/ib_insync/commit/5835745dba24bc0162d95404a3c3071d0fa3ba62

ibapi seems not to be maintained actively, there were many updates in ib_incync over the last two years

sources on IB site use Decimal for volume representation, e.g:

def realtimeBar(self, reqId: TickerId, time:int, open_: float, high: float, low: float, close: float, volume: Decimal, wap: Decimal, count: int):

this is not the case for ibapi taken from "pip install":

def realtimeBar(self, reqId: TickerId, time:int, open_: float, high: float, low: float, close: float, volume: int, wap: float, count: int):

I fixed this locally by installing sources from IB site AND by edding extra default argument in vnpy_ib / ib_gateway.py:

def error(self, reqId: TickerId, errorCode: int, errorString: str, advancedOrderRejectJson: str = "") -> None:
