Fix AuthSessionMissingError
in Supabase JS
✅ Solution
The "AuthSessionMissingError" in supabase-js usually arises when the client attempts to access or manipulate authentication state (like signing out) before the initial authentication session has been established or after it has expired/been cleared unexpectedly. To fix this, ensure your app properly initializes Supabase auth on startup, checks for an existing session, and handles session expiry gracefully by re-authenticating or redirecting the user to login if necessary before attempting operations like `signOut`. Consider using `supabase.auth.getSession()` to check the session state before calling `signOut`.
