Solutions

3 solutions available

1. Specify a Valid ACL LOG Subcommand easy

The most direct solution is to provide the required subcommand when using the ACL LOG command. The common subcommands are LIST and RESET.

1
When you encounter the 'ERR ACL LOG requires a subcommand' error, review your command and ensure you are appending a valid subcommand.
ACL LOG LIST
2
Alternatively, if you intend to clear the log, use the RESET subcommand.
ACL LOG RESET

2. Verify Redis ACL Configuration and Usage medium

This error can sometimes indicate a misunderstanding of how Redis ACLs function or an incorrect implementation of ACL commands. Ensure you are familiar with the Redis ACL command syntax.

1
Consult the official Redis documentation for the ACL command to understand its structure and available subcommands.
https://redis.io/commands/acl/
2
If you are writing scripts or applications that interact with Redis ACLs, double-check the logic for constructing ACL LOG commands. Ensure that the subcommand is correctly appended based on the intended operation.
Example of incorrect usage (leading to the error):
`redis-cli ACL LOG`

Example of correct usage:
`redis-cli ACL LOG LIST`

3. Check Redis Version Compatibility medium

While less common for this specific error, ensure your Redis version supports the ACL LOG command and its subcommands. ACLs were introduced in Redis 6.0.

1
Determine the Redis version you are running. You can typically do this by connecting to Redis with redis-cli and running the INFO command, then looking for the 'redis_version' field.
redis-cli
INFO redis_version
2
If your Redis version is older than 6.0, you will not have access to ACL commands. In this case, you will need to upgrade your Redis instance to a version that supports ACLs.
Refer to Redis installation guides for your specific operating system for upgrade procedures.
