NOPERM error

The user is authenticated but isn't allowed to run the command or use the key.

Redis returns this error when you're authenticated, but your user's access control list (ACL) rules don't allow what you asked for. The message says what was refused, a command or a key:

NOPERM User app has no permissions to run the 'set' command
NOPERM No permissions to access a key

In redis-py, this error is NoPermissionError, followed by the message without the NOPERM prefix.

Example

The user app can only run GET, and only on keys that start with allowed::

> ACL SETUSER app on ><password> +get ~allowed:*
OK
> AUTH app <password>
OK
> SET allowed:1 "x"
(error) NOPERM User app has no permissions to run the 'set' command
> GET other
(error) NOPERM No permissions to access a key

How to fix it

1. Find out what was refused. As an administrator, run ACL LOG. Each entry shows the user, the reason, such as command or key, and the object, which is the command or key name.
2. Check which user your app is connected as with ACL WHOAMI.
3. Connect as a user that has the permission, or change the user's rules with ACL SETUSER. For example, ACL SETUSER app +set lets the user run SET, and ACL SETUSER app ~other lets it use the key other.
