Basically it means that instead of trying to fetch the weather-background-above_horizon.png it’s fetching weather-background-{{states('sun.sun')}}.png. So really it’s “Templating not being applied”
Huh…
Anyway, at this point, I’d recommend filing an issue over at card-mod’s GitHub, because if it works, then really the only bug is that you have unnecessary stuff in your log.
This is because the unprocessed string is used first, and then replaced with the template result once it returns from the backend.
The error can be safely ignored so long as it works, and when it doesn’t, this will help you find the problem.
thanks Thomas. Does this mean we keep seeing errors on jinja templates from now on in the inspector? Or would you be able to prevent this (seeing this is new behavior, and didnt show before on card tools 1)
Would be really nice if you could somehow manage that. Or, of course, have us use other techniques templates maybe, that are a preferred method.
