Since 2026.6 By Card Picker empty and paste function broken

Hi everyone,

I’m running into a strange issue with the dashboard editor since the recent updates,

The Issue:

  • When I try to add a card or a badge using the "By Entity" tab, everything works perfectly.
  • However, when I switch to the "By Card" tab, the list is completely empty. No cards are displayed or listed at all.
  • Additionally, it is impossible to paste a card that I previously copied to the clipboard.

What works:

  • If I create a brand new dashboard from scratch using the Sections layout, the card picker works flawlessly, and I can see/paste cards without any issue.

It seems this bug only triggers on older dashboards that went through the migration process to the Sections view.

Environment details (example):

  • Home Assistant Core: 2026.6.
  • Browser used: latest version of Chrome and Firefox

Has anyone else experienced this? Are there any known workarounds to "refresh" the migrated dashboard configuration without having to rebuild it from scratch?

Thanks for your help!

I believe this implies you have some broken yaml somewhere on that dashboard. If you search for - null in the yaml view for the dashboard, do you find anything?

There's a bug when this is encountered that breaks the add card flow (since it scans your dashboard first to look for entity suggestions). A bugfix has been prepared for 2026.7.

That's why it works again if you switch to a different dashboard that doesn't have the bad yaml.
