check this:

Set_ruleset Folder configuration_hash does not exist

Yes, if i remember it correctly then the configuration hash is used by the system to check if something is changed or not. Your hash is a hash of a empty rule, i think there could be a logic problem if the existing rule is empty

ANd you have to use get_ruleset and then set_ruleset, you need the configuration_hash ID its very important
