Assistance with Vertical Stacks and Custom Cards

Hello,

I’m fairly new to Lovelace, and I’ve been struggling a bit with two vertical-stack cards that are both part of the same main view.

Both vertical stacks contain custom cards, at least one of which (the alarm panel card) was loading properly previously.

Right now, for both of the vertical stack cards I’m getting the JS error:

“Cannot read property ‘states’ of undefined”

I’m hoping that someone can take a look at my YAML and see where I goofed (most likely in the spacing, but I just can’t see it).

Thanks!

assuming you’re on 0.81.0, there’s a nasty bug (red screens). Should be fixed soon with 0.81.1 hotfix.

Thanks @DavidFW1960. I appreciate the heads up. Is there a link to the GitHub bug report?

I think I was able to answer my own question. I’ll leave this here in case anyone else is looking for the GitHub bug report:
