Data Not Saving to Database in My AI App

You fill out a form or perform an action in your app, it looks like it works, but when you refresh the page the data is gone. The database isn't saving anything, or data disappears after a page reload.

Error Messages You Might See

new row violates row-level security policy relation does not exist column does not exist 42501: permission denied 23505: duplicate key value violates unique constraint

Common Causes

Database connection is failing silently
Row Level Security (RLS) policies are blocking inserts/updates
The app is saving to local state but not making the API call to the database
Database table structure doesn't match what the app is trying to save
Missing or wrong database URL in production environment variables

How to Fix It

Open browser Network tab (F12 > Network) and watch for API calls when you submit data — check for errors
If using Supabase, go to the SQL editor and check if the table exists and has the right columns
Check RLS policies — they're the #1 cause of data not saving in Supabase apps
Verify your database connection string in environment variables
Check the server/API logs for database errors

Frequently Asked Questions

Data saves but disappears after refresh. What's happening?

The app is probably saving to local state (React state, for example) but not actually calling the database API. Check the Network tab for API calls when you submit.

I see a 'row-level security' error. What does that mean?

RLS is a Supabase feature that controls who can read/write data. The AI probably created tables without proper RLS policies. You need to add policies that allow your users to insert and read their own data.
