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

Nam Tran 10 years as fullstack developer

hanson1014 Full-stack developer experienced in fixing and deploying AI-generated apps from Lovable, Bolt.new, Cursor, and Replit. I specialize in debugging Supabase integration issues (auth flows, RLS policies, database connections), fixing broken deployments, resolving routing/blank screen problems, and cleaning up messy React/Vite codebases. I also build production apps with the Claude API and have shipped a Mac desktop dev tool (Nexterm from scratch. Based in Hong Kong, fast turnaround.

Alvin Voo I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing. My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream. What I bring to your project: Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins. Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams. Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

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.
