🐛 Describe the bug

When you execute a turn after creating agent_id and session_id, the error comes as zrangebylex method throws an error with the error being that 1 argument is missing. This is happening because we are not using sorted_sets, we are just setting the values using keys. Because of that we do not have a name for the sorted set, so its causing an error.

TypeError: SortedSetCommands.zrangebylex() missing 1 required positional argument: 'max'

Expected behavior

No error, just turn should be created
