Lovable Supabase not working
Supabase issues in Lovable usually come from authentication state, missing environment variables, table schema mismatches, row-level security policies, storage permissions, or edge function errors. The safest fix starts by isolating which layer is failing.
Quick verdict
When Supabase is not working in Lovable, identify whether the failure is auth, database, RLS, storage, secrets, or edge functions before prompting for a fix.
Target topics covered
Name the failing layer
Supabase is not one thing. It can involve auth, tables, policies, storage, realtime, edge functions, and environment variables. A good fix starts by identifying the layer that fails first.
- Auth: user cannot sign up, log in, or stay logged in
- Database: rows are missing, duplicated, or not saved
- RLS: users get permission denied or see the wrong records
- Storage: uploads fail or images do not load
- Edge functions: server action fails or returns an error
- Secrets: API keys or environment variables are missing
Be careful with reverts
Database schema changes do not always revert as cleanly as UI changes. Before rolling back, ask Lovable to validate table structure, policies, and data expectations so you do not break the current database state.
Use logs for edge functions
If an edge function fails, check the Cloud tab logs or the visible error details. Missing secrets, invalid database calls, auth session problems, and malformed request bodies are common causes.
Supabase fix prompt
The Supabase flow on [page] is failing. Expected: [result]. Actual: [result/error]. Please identify whether the issue is auth, RLS, table schema, storage, secrets, or edge functions. Fix the smallest cause and do not change unrelated tables or policies.
Frequently asked questions
Why is Supabase not working in my Lovable app?
Common causes include incorrect auth state, missing environment variables, table mismatch, row-level security policies, storage permissions, or edge function errors.
What is RLS in Supabase?
RLS means row-level security. It controls which users can read, insert, update, or delete records. Incorrect policies can block valid users or expose the wrong data.
Should I revert a Lovable app with Supabase changes?
Be careful. UI reverts are often simpler than database reverts. Ask Lovable to verify schema and policies before rolling back database-linked work.
