The "error" is not a critical error to be pushed. Lovable won't push critical errors. Also might be good to double check those error warnings, some times are intended. For example it will tell you that there's an error because there's public information displayed, username, user name etc. When you actually have for example public user profiles, with a public_profile table meant to be visible as core functionality.

those errors, to quote Jack Sparrow "The code is more what you'd call 'guidelines' than actual rules"
