Can I clear the error state using `json_해제_error()`?

Yes, you can. The `json_해제_error()` function resets the `json_last_error()` variable to `JSON_ERROR_NONE`. This is useful if you want to allow the script to continue running after an error and potentially handle the error later or if you are in a situation where you want to suppress the error reporting temporarily (though this should be done with caution).
