Cannot install plugs

I’m trying to reinstall treeview, but I’m unable to add any plugs. I go to “Plugs: Add”, insert the url, and “Plugs: Update”, but I get an error “PLUGS YAML does not contain a plug list, not loading anything”.

I also tried manually adding it into the PLUGS page with the same result.

I’m running in docker, and I don’t see any errors in the logs. I’ve tried in Firefox, Vivaldi, and Chrome, and I disabled anything I could think of that may be blocking it. Any ideas? Thanks!

Fixed it by deleting and letting silver bullet recreate it.
