I have a business rule when a parent state is updated it will updated the related child record states now the issue is when the parent have no child records I'm showing an error "No child records present" otherwise I'm updating the child records. here issue is even after having the child records under a parent still it is showing error message and updating the state both things are running what mistake I made help me
when to run  "AFTER UPDATE"

(function executeRule(current, previous /*null when async*/ ) {

    if (previous.state != current.state) {

        var fo = new GlideRecord('x_1086067_financia_financial_object');

        fo.addQuery('parent', current.sys_id);

        fo.query();

        if (fo.hasNext()) {

            while (fo.next()) {

                fo.state = current.state;

                fo.update();

            }

        }else {

        gs.addErrorMessage('No child recods present');

update as this

(function executeRule(current, previous /*null when async*/ ) {
    if (previous.state != current.state) {
        var childRecords = new GlideRecord('x_1086067_financia_financial_object');
        childRecords.addQuery('parent', current.sys_id);
        childRecords.query();
        var hasChildren = false;
        while (childRecords.next()) {
            hasChildren = true;
            childRecords.state = current.state;
            childRecords.update();
        }
        
        if (!hasChildren) {
            gs.addErrorMessage('No child records present');
        }
    }
})(current, previous);
