Supabase Auth User Session Not Found

The session ID provided does not match any active session.

Understanding Supabase Auth

Supabase Auth is a powerful authentication tool designed to manage user authentication and authorization in your applications. It provides a seamless way to handle user sessions, manage user data, and integrate with various authentication providers. Supabase Auth is part of the Supabase suite, which aims to offer a complete backend solution for developers.

Identifying the Symptom: User Session Not Found

When working with Supabase Auth, you might encounter an error message stating 'User Session Not Found'. This issue typically arises when the system cannot locate an active session corresponding to the provided session ID. As a result, users may experience unexpected logouts or be unable to access certain features of your application.

Exploring the Issue: Why 'User Session Not Found' Occurs

The 'User Session Not Found' error indicates that the session ID being used does not match any currently active session in the Supabase Auth system. This can happen for several reasons, such as:

  • The session ID is incorrect or has been mistyped.
  • The session has expired or been terminated.
  • There is a synchronization issue between the client and server.

Understanding these potential causes can help in diagnosing and resolving the issue effectively.

Steps to Fix the 'User Session Not Found' Issue

Step 1: Verify the Session ID

Ensure that the session ID being used is correct. Double-check the ID for any typographical errors or inconsistencies. You can log the session ID on the client-side to verify its accuracy before sending it to the server.

Step 2: Check Session Expiry

Sessions in Supabase Auth have a limited lifespan. Verify whether the session has expired by checking the session's expiry time. You can do this by querying the session details using Supabase's API:

const { data, error } = await supabase.auth.getSession();
if (error) {
console.error('Error fetching session:', error);
} else {
console.log('Session data:', data);
}

If the session has expired, prompt the user to log in again to establish a new session.

Step 3: Ensure Synchronization

Ensure that there is proper synchronization between your client and server. Network issues or delays can sometimes cause discrepancies in session management. Implement error handling to manage such scenarios gracefully.

Step 4: Review Server Logs

Check your server logs for any errors or warnings related to session management. Logs can provide valuable insights into what might be causing the session to be unrecognized.

By following these steps, you should be able to resolve the 'User Session Not Found' issue effectively and ensure a smooth authentication experience for your users.
