I’m joining the crowd here also with this recently new error message. I use a separate config file for light groups. In the file I designate a platform: switch, which returns an error, “Unable to load schema from ‘http://schemas.home-assistant.io/integration-light’: No content.”
Reading other threads, it sounds like this is a bug in Studio Code Server. Everything seems to be working fine despite the error.
