HI @String ,
I trust you are doing great.
Here’s a modified version of your script with additional logging. This might help in understanding what data is available at the time of the rule execution:

(function executeRule(current, previous /*null when async*/) {
    // Log current record to see all available fields
    gs.info("Current KB Record: " + JSON.stringify(current));

    // Check if version is available
    var version = current.getValue("version");
    if (version) {
        gs.info("Version: " + version);
    } else {
        gs.info("Version not available at this point");
    }
})(current, previous);
