Fix ReadOnlyError

✅ Solution

The "ReadOnlyError" in redis-python usually arises when attempting write operations (e.g., SET, DEL) on a Redis instance configured as a read-only replica. To fix this, ensure your write operations are directed to the master instance. If using Sentinel, verify that your connection is correctly configured to connect to the master and not a read-only replica, potentially by specifically requesting the master's address.
