link is not setting to another issue in post function of "Create" transition

[zaharovvv_suek_ru]

I am creating an issue from Confluence page. So there is a link to a Conluence page at newly created Jira issue:

I've created a post function and put this function on the last place of excution afer "Re-index an issue to keep indexes in sync with the database",
"Fire a Issue Created event that can be processed by the listeners." functions:

My code in post function:

def log = Logger.getLogger("com.acme.CreateSubtask")
log.setLevel(Level.DEBUG) 

Logger.println('Start')
def rlm = ComponentAccessor.getComponent(RemoteIssueLinkManager)
log.info('1')
def links = rlm.getRemoteIssueLinksForIssue(issue)

Logger.println("Starting links print")
log.info('2')
def onlyConflueceLinks = links.each {
 log.info('3')
 if (it.applicationType == RemoteIssueLink.APPLICATION_TYPE_CONFLUENCE) { 
 // getting pageId
 log.info('4')
 def confluenceUrl = it.getUrl(); 
 log.info('confluenceUrl: '+ confluenceUrl)
 def pageId = confluenceUrl.substring(confluenceUrl.lastIndexOf('=') + 1) 
 def isNumber = false;
 try{
     if(Integer.parseInt(pageId)){ 
         pageId = Integer.parseInt(pageId) 
         isNumber = true;
     }
 }
 catch(NumberFormatException e) {
     log.info('Not a number!')
 } 
 // get issues at Confluence page by pageId
 if(isNumber){
 log.info('5')
 def jqlQueryParser = ComponentAccessor.getComponent(JqlQueryParser)
 def searchProvider = ComponentAccessor.getComponent(SearchProvider)
 def issueManager = ComponentAccessor.getIssueManager()
 def user = ComponentAccessor.getJiraAuthenticationContext().getUser()
 def jqlSearch = "issue in (issuesWithRemoteLinksByGlobalId('appId=710bf4d7-7ee9-3527-bbe8-a27bb56c2fa2&pageId=${pageId}')) and issuetype=10000"
 def query = jqlQueryParser.parseQuery(jqlSearch)
 def searchResult = searchProvider.search(query, user, PagerFilter.getUnlimitedFilter())
 // if there is an issue
 if(searchResult.total > 0) {
    log.info(searchResult.issues.first()) 
    def epicIssue = issueManager.getIssueObject(searchResult.issues.first().id)
    log.info('epic issue is ' + epicIssue)
    ef currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser() 
    def linkMgr = ComponentAccessor.getIssueLinkManager()
    log.info('issue is '+ issue)
    log.info('epicIssue is ' + epicIssue) 
    linkMgr.createIssueLink(issue.getId(), epicIssue.getId(), 10334, 1, currentUser) 
 } 
 } 
 }
}

What I see in logs are just: 
1
2

How is it possible to set link to another issue in post function of "Create" transition?
