I did the suggested update yesterday to the frigate card 6.0 beta on the latest version of Home assistant with the latest version of the frigate integration running haos. I restarted home assistant and now the cameras from my card no longer display, just lots of text.
I can’t find any documentation for the upgrade showing breaking changes or any place to post issues so I’m leaving this here.
Going into the frigate addon itself, the cameras appear perfectly.
