@NIcollas Viggiano - Ah just realized there was a typo in my script. Please try below

(function runMailScript(/* GlideRecord */ current, /* TemplatePrinter */ template,
          /* Optional EmailOutbound */ email, /* Optional GlideRecord */ email_action,
          /* Optional GlideRecord */ event) {
   
    var record = new GlideRecord('sc_req_item');
    var sysCurrentRecordSysId = current.sys_id;
    record.addQuery('sys_id', sysCurrentRecordSysId);
    record.query();
	while (record.next()) {
        var mrvs = current.variables.request_information; //update with your variable set name
        var objectCount = obj.getRowCount();
	for(var i=0; i< objectCount .length; i++) {
        var row = mrvs.getRow(i)
	template.print('<br/>' + 'System: ' + row.system_name); 
	template.print('<br/>' + 'Profile: ' + row.profile_name);
	template.print('<br/>' + 'Approver: ' + row.aprovador_do_perfil);
		}
	}
}

)(current, template, email, email_action, event);
