sciptrunner ignor by few users

[destis]

hi.

i have script

if ( groupManager.isUserInGroup(issue.getAssigneeId(), "IT")) {issue.setSecurityLevelId(10011); issue.setAssignee(userUtil.getUserObject("user"));}

but some users ignored by this script. group - checked, secutirylevelid - checked..

i think it because this users was renamed.
scipt takes issue.getAssigneeId from app_user database table?
