TransitionValidation fails in create issue listener

[Oleksii Okhmush]

Hello everyone!

I try ty make a script, that creates user in Jira, added comment to task with login/password and then close the issue.

If i try it in Script Console everything works fine, but if i try to use Script Listener with "Issue created" event, i can't transition issue

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.fields.CustomField
import com.atlassian.jira.event.type.EventDispatchOption
import com.atlassian.jira.bc.user.UserService
import com.atlassian.jira.issue.IssueInputParametersImpl
def customFieldManager = ComponentAccessor.getCustomFieldManager()
def admin = ComponentAccessor.getUserManager().getUserByKey('admin')
def commentManager = ComponentAccessor.commentManager
def userService = ComponentAccessor.getComponent(UserService)
def userUtil = ComponentAccessor.getUserUtil()
def issueService = ComponentAccessor.getIssueService()
final boolean sendNotification = false
Issue issue = issue as Issue
if (issue.issueType.name=="New user") {
    String email = issue.getCustomFieldValue(customFieldManager.getCustomFieldObject("customfield_11700"))
    String name = issue.getCustomFieldValue(customFieldManager.getCustomFieldObject("customfield_11702"))
    List email_list
    String login
    String password = "123456789"
    def actionId = 11
    def transitionValidationResult = issueService.validateTransition(admin, issue.id, actionId, new IssueInputParametersImpl())
    def group = userUtil.getGroup("cw-freelance")
    if (email =~ /^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$/) {
        email_list = (email =~ /^([a-zA-Z0-9_\-\.]*)/)[0] as List
        log.warn(email_list)
        login = email_list[0] as String
        log.warn(login)
        def user = ComponentAccessor.getUserManager().getUserByKey(login)

        if (!user) {
            def newCreateRequest = UserService.CreateUserRequest.withUserDetails(admin, login, password, email, name)
                .sendNotification(sendNotification)

            def createValidationResult = userService.validateCreateUser(newCreateRequest)
            assert createValidationResult.isValid(): createValidationResult.errorCollection

            userService.createUser(createValidationResult)
            def new_user = ComponentAccessor.getUserManager().getUserByKey(login)
            userUtil.addUserToGroup(group, new_user)
            commentManager.create(issue, admin, "Новый пользователь:\nlogin: " + login + "\npassword: " + password, true)
            issueService.transition(admin, transitionValidationResult)
        } else {
            commentManager.create(issue, admin, "пользователь уже существует: " + user.displayName, true)
            issueService.transition(admin, transitionValidationResult)
        }

    } else {
        commentManager.create(issue, admin, "Ошибка в почте", true)
        log.warn("bad email")


    }

}else{
    return null
}

What should i do, to avoid this?
