Pls advise script action not trigger into the line indexof

[BanuMahalakshmi]

Hi,

I have attached system log, the business rule fetching CI sys id and current user id(from user table). 

event triggered, script action. but the script execution failed into the line indexof. index value printing -1 still though it has value. kindly let me know the correction in the script:

Business Rule:

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

   var userSysId = current.sys_id.toString();

    var civalue;

    var gr1 = new GlideRecord('cmdb_ci');

    gr1.addQuery('u_level_1_approver', 'CONTAINS', userSysId);

    gr1.query();

    while (gr1.next()) {

        civalue = gr1.sys_id;

        gs.log("the ci value=" + civalue);

        gs.log("the user sysid=" + userSysId);

        gs.eventQueue("remove.user", gr1, civalue, userSysId);

    }

})(current, previous);

 Event Trigger: into CMDB_CI table

Script Action:

gs.log(event.parm1);

gs.log(event.parm2);

deactivateuser(event.parm1, event.parm2);

function deactivateuser(id, username) {

    var approverarray = [];

    //var index = -1;

    var gr = new GlideRecord("cmdb_ci");

    gr.addQuery('sys_id', id);

    gr.query();

    while (gr.next()) {

        var approver = gr.getValue('u_level_1_approver');

        approverarray = approver.split(',');

        gs.log("the approver array=" + approverarray);

        gs.log("the username=" + username);

        var index = approverarray.indexOf(username);

        gs.log("index=" + index);

        if (index != -1) {

            approverarray.splice(index, 1);

            gs.log("the array=" + approverarray);

            gr.u_level_1_approver = approverarray;

            //  gr.setValue('u_level_1_approver', approverarray.join(','));

            gr.update();

        }

    }

}
