Exceptions with 26.4.2 - Due to custom panels?

Developers WeatherFlow PiConsole

I updated my console to 26.4.2, along with all the system updates and now I get a bunch of exceptions. I built several custom panels a few months ago and I suspect that they might not be playing well with the latest update. Can you look at the errors and tell me if it’s a customization issue or something else?

If it’s my poor coding, I’ll remove the customizations and work on them when I have time.

Thanks!

Thanks! I’ll make the changes.
