Hello,
On my Rapberry-Pi (Home Assistant Supervised 2020.12.0) on Raspbian, for a while now, the dashboard “Overview” doesn’t appear anymore, I only have a blank page.
Same problem on Firefox and in the Android application.
The js console keeps returning this error only in the Overview dashboard:
Uncaught (in promise) TypeError: this.lovelace is undefined
Uncaught (in promise) TypeError: undefined has no properties
Other dashboard added works well
The dashboard “Overview” showed me all the Entities discovered.
How can I reset this dashboard ?
