Behaviours error after migration JIRA server 8.5

BYA_txu2pw

Hello, 

we migrated from JIRA 7 to 8.5.

Now I have errors with a behavior that work great before migration.

import com.atlassian.crowd.embedded.api.User
import com.atlassian.jira.component.pico.ComponentManager
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.MutableIssue

ComponentManager componentManager = ComponentManager.getInstance()
Object fieldID = getFieldById("Application")

MutableIssue currentIssue = componentManager.getIssueManager().getIssueObject(Long.parseLong(fieldID.value))

FormField pr_field = getFieldById("Application")

def isPR = componentManager.getUserUtil().getGroupNamesForUser(currentIssue.getReporter
User().getDisplayName()).contains("Groupe-P2B-Application_2")

if(!isPR){
pr_field.setHidden(false)
pr_field.setRequired(true)
}

 help please ? 

Thanks,

BR
