create a fix script to add evt_mgmt_operator role to itil , getting errors

[ServNowDev]

addRoletoRole();

function addRoletoRole(){
    // Find the ITIL role
    var itilRole = new GlideRecord('sys_user_role');
    itilRole.addQuery('name', 'ITIL');
    itilRole.query();

    if (itilRole.next()) {
        // Check if the evt_mgmt_operator role already exists in ITIL role
        var itilRoles = itilRole.getValue('roles');
        if (itilRoles.indexOf('evt_mgmt_operator') === -1) {
            // Add evt_mgmt_operator role to the ITIL role
            var newRoles = itilRoles + ',evt_mgmt_operator';
            itilRole.setValue('roles', newRoles);
            itilRole.update();
            gs.info('evt_mgmt_operator role added to ITIL role successfully.');
        } else {
            gs.info('evt_mgmt_operator role already exists in ITIL role.');
        }
    } else {
        gs.error('ITIL role not found.');
    }
}

getting error below:

Evaluator: com.glide.script.RhinoEcmaError: Cannot convert null to an object.
   script : Line(12) column(0)
      9:     if (itilRole.next()) {
     10:         // Check if the evt_mgmt_operator role already exists in ITIL role
     11:         var itilRoles = itilRole.getValue('roles');
==>  12:         if (itilRoles.indexOf('evt_mgmt_operator') === -1) {
     13:             // Add evt_mgmt_operator role to the ITIL role
     14:             var newRoles = itilRoles + ',evt_mgmt_operator';
     15:             itilRole.setValue('roles', newRoles);

unfortunately ive suggested but this is so far what they want to accomplish role to role, no role to groups or custom role to role , itil users need the evt_mgmt_operator role and its not allowing me to add

Hi @ServNowDev 

I got the Root cause why you are not able to add evt_mgmt_operator to itil role

The evt_mgmt_operator role contains itil role already indirectly.

That is why you would be getting the cyclicity error

[Manmohan K · Accepted solution]

Explanation:

evt_mgmt_operator contains evt_mgmt_user role

evt_mgmt_user contains sam_core_user role

sam_core_user contains itil role

So itil is already contained inside evt_mgmt_operator

Awesome, thanks so much didnt catch that , simple remove of sam_core_user fixed my issue it now attaches thanks a ton!!
