}

def main():
    exchange.GetOrder("123")
    error = GetLastError()
    Log(error)

void main() {
    // Order ID type: TId, so you can't pass in a string, we place an order that doesn't meet the exchange specification to trigger
    exchange.GetOrder(exchange.Buy(1, 1));
    auto error = GetLastError();
