Optimize method fails w/o any error info

[Chidifinance]

Expected behavior

I try to optimize a set of args, it fails. But it doesn’t show what the error is. A simple backtest runs, so I know that’s fine. I’ve tried printing to console with try/except in init & super. But nothing. Dunno how to tell what exactly the issue is if I don’t get errors

Code sample

Actual behavior

It just shows a failed bar. Instead of either actually working or showing the error stack
