Rendering of dashboard in HA fails when one of sensors is not given about air-visual-card HOT 3 CLOSED

I tested your change but it caused a crash. Can you double-check that this change works on your end?

Hey @dnguyen800 , sorry I couldn't verify that once again because currently I'm doing a reconfiguration of my HA instance.

What I can say is that the fix I proposed just solved my problem. In my case the sensor.config property was null because I didn't pass on of sensors in Lovelace configuration.

Can you please give me some details of error and an use case to reproduce it? To be honest I'm a backend developer and I didn't care much about browser compatibility 🙄

Maybe that's the reason?

I'm not a programmer and never actually learned Javascript (besides looking at other people's examples, so I have a lot of gaps in knowledge unfortunately...

What I wanted to understand was in this line of code (see below), you added a question mark '?', but I wasn't sure what it does. It's hard to search online for what a ? means in code, haha. I tried using the fix in my instance and it crashed the UI, though maybe I should double-check again if it works on your end.

if (sensor.config?.split('.')[0] == 'sensor')
