How to Fix “RLS Policy” in Supabase (2026 Guide)

The Short Answer

To fix the “RLS Policy” error in Supabase, advanced users can toggle off the Row-Level Security (RLS) policy in the Settings > Authentication > Row-Level Security section, and then refresh the page. This will temporarily disable the permission check, allowing you to access the database, but it’s essential to address the underlying issue to ensure data security.

Why This Error Happens

  • Reason 1: The most common cause of the “RLS Policy” error is a misconfigured RLS policy, where the permissions are not correctly set for the user or role, resulting in a database error when trying to access the data.
  • Reason 2: An edge case cause of this error is when the RLS policy is not properly updated after changes to the database schema, leading to a mismatch between the policy and the actual database structure, causing the error.
  • Impact: The “RLS Policy” error can lead to a Database Error, preventing users from accessing the data, and potentially causing issues with applications that rely on the database.

Step-by-Step Solutions

Method 1: The Quick Fix

  1. Go to Settings > Authentication > Row-Level Security
  2. Toggle Enable Row-Level Security to Off
  3. Refresh the page to apply the changes.

Method 2: The Command Line/Advanced Fix

To fix the RLS policy using the Supabase CLI, you can use the following command:

1

UPDATE pg_catalog.pg_namespace SET nspacl = '{supabase_admin=UC/supabase_admin}' WHERE nspname = 'your_schema_name';

Replace your_schema_name with the actual name of your schema. This command updates the namespace ACL to grant the supabase_admin role the necessary permissions.

Prevention: How to Stop This Coming Back

To prevent the “RLS Policy” error from occurring in the future, follow these best practices:

  • Regularly review and update your RLS policies to ensure they align with changes to your database schema.
  • Use the Supabase CLI to manage your RLS policies, as it provides more fine-grained control over the permissions.
  • Monitor your database logs for any errors related to RLS policies, and address them promptly to prevent issues.

If You Can’t Fix It…

[!WARNING] If Supabase keeps crashing due to the “RLS Policy” error, consider switching to PostgreSQL, which handles permission checks natively without these errors. However, this should be a last resort, as Supabase provides many benefits, including ease of use and scalability.

FAQ

Q: Will I lose data fixing this? A: No, fixing the “RLS Policy” error should not result in data loss, as it is a permission-related issue rather than a data corruption issue. However, it’s always a good idea to back up your data before making any changes to your database.

Q: Is this a bug in Supabase? A: The “RLS Policy” error is not a bug in Supabase, but rather a configuration issue. Supabase provides a robust RLS system, and the error is usually caused by a misconfiguration or a mismatch between the policy and the database schema. As of version 1.4.0, Supabase has improved its RLS policy management, making it easier to configure and manage permissions.
