Just for information if my radarr and sonarr integration working fine, if i put the card type again, it will completely disappear like above

My dashboard was not loading at all after updating Home Assistant to core-2021.4.5
I troubleshoot the lovelace by removing custom add-ons and see which one was causing the crash. It was the upcoming-media-card, after removing it from the RAW configuration editor the UI loaded and everything was working fine.

I had the same thing, but fixed it with reinstalling. I think something changed with integration. IIRC, the js files are stored somewhere else, so if you follow the installation instructions, the resources have moved. I then put the cards back in the dashboard and it worked.

the built in sonarr component integration does not supply this front_end card with the correct json data its programmed to look for..
this is why is doesn't work

you have to use the sonarr integration from here (not the built in HA integration)
https://github.com/custom-components/sensor.sonarr_upcoming_media

you can about it here https://github.com/custom-cards/upcoming-media-card/blob/master/troubleshooting.md#components

I realize that this was my fault for not reading the directions properly when adding everything, but would it be possible to have attempting to use the default HA implementation cause a visible error? I made this mistake as well as Bios-Dude and I'm guessing that others have as well and possibly just give up and move on.

In HA version 2021.10.0 the Trakt integration failed to load in my case (see issue). And I assume now after reading this that that also caused that the Lovelace Dashboards did not show at all. A front end component should never cause that kind of impact when the integration that it depends on is not available. The error should be isolated and only the component itself should be impacted.
