Latest Update made the Card go blank and causes the Overview page to go Blank too

[LokeYourC3PH]

What the title says. After updating to the latest version about 9-10 hours ago, the card is now completely blank, and the Dashboard/Overview panel where it is located also does not show up until I do a CTRL+F5 to force reload it. Then I can see everything, and the card itself is basically a 1px empty line, and I had to configure the Dashboard/Overview to remove it for everything to work normally again.

Note: Adding it back manually after removing it makes the Dashboard go completely blank and you need to remove it via the "Raw Configuration Editor". This is pretty bad.

Which integration are you using?

Didn't get it at first, my bad.

HACS, I use the HACS version.

I've got something from the raw logs that might help:

Chiming in that I'm seeing the same thing. I use Home Assistant Sections and the entire section containing the card becomes blank. The rest of my dashboard was unaffected, just the section containing the card. Editing the Section in YAML mode to remove the card fixed the Section, though as with the original issue reporter, trying to re-add the card only causes it to fail to render again.

I'm seeing the following console error in the frontend when the card is on the page:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'attributes')
    at set hass (air-visual-card.js?hacstag=157674859204:396:68)

The problem on this line:

air-visual-card/dist/air-visual-card.js

Line 396 in 202fba6

if (weatherEntity != '' && typeof hass.states[weatherEntity].attributes['wind_speed_unit'] != "undefined"){

You're checking to make sure that weatherEntity is defined, there's no check to make sure that hass.states[weatherEntity] exists. This is happening because you're using weather.home as the default weather value on this line:

air-visual-card/dist/air-visual-card.js

Line 41 in 202fba6

weather: "weather.home",

My weather entity has a different id. So the if statement sees the default value of weather.home you've provided in the config, but if the end-user has a different weather entity name, this will fail because there is no state for this non-existant entity.

The best solution, honestly, is probably not to set a default weather entity value, and just leave it blank by default. But since many users probably already have this non-existent entity in their configs due to this default, you'll need to confirm that the entity exists, unless there's a way to do a config migration to remove weather.home if it doesn't exist. IDK how much power HACS gives you to modify existing configs.

[Chreece]

Yes you are right, the weather entity check should return '' if no none is given.
I will try to make a PR in the afternoon to fix that problem. Sorry for that 😔

[Chreece]

Could you please test the card from my repo:
https://github.com/Chreece/air-visual-card
Please clean browser cache afterwards (shift+f5)

[LokeYourC3PH]

I mean in my case, my weather integration is PirateWeather, which is quite different from (and better in every way) the default weather integration, which if this card requires the default weather integration to be present all of a sudden, would make sense for why it fails.

The entity ID for it is "weather.pirateweather", which I hope to use in the stead of the default one.

@LokeYourC3PH still after the changes on my repo you have the same error?

I only use HACS and never manually install plugins, so I cannot test your repo. Gotta wait for ytilis to confirm.

[Chreece]

HACS is using repos though.
But I understand, you can wait for others to test...

You're right, I could try to manually add your Repo and see if it works, no promises though 👍

EDIT: Hmm, getting an error trying to add your Repo:

[Chreece]

It's not an integration but front-end, I don't know how it's in English

I see, there's the following options:

According to what you say, I would assume Dashboard, so I will try that.

EDIT: Seems like Dashboard works, I will try the plugin now.

[Chreece]

Exactly, dashboard
