unable_to_create_session
The session could not be created during authentication.
What is it?
This error occurs when Better Auth fails to create a session after a successful authentication step. A session is required to keep the user logged in, so failure to create one results in this error.
Common Causes
- Database write failure when creating the session record.
- Session store misconfiguration.
- Connection issues or timeouts with the database.
- Invalid or missing session-related fields.
- Errors in custom hooks or adapters affecting session creation.
How to resolve
Verify database and session storage
- Ensure your database or session store is properly configured and reachable.
- Check for connection errors or timeouts.
Check schema and migrations
- Confirm that session-related tables/collections exist and are up to date.
Review configuration
- Verify your Better Auth configuration for session handling.
Inspect logs
- Look for errors during session creation in server logs.
