NullPointerException error on Groovy Script

[Sandhya Muthukumar]

I am a Jira Admin and I am trying to add users to project roles using Groovy Script

But it is throwing an error Null Pointer Exception on addActorsToProjectRole, eventhough all the inputs have values except for error collection

projectRoleService.addActorsToProjectRole(currentUser,usersToAdd as Collection,projectRoles,projectKey,userRoleActor,errorCollection)

ERROR:

Script console script failed: java.lang.NullPointerException at com.atlassian.jira.bc.projectroles.DefaultProjectRoleService.createRoleActors(DefaultProjectRoleService.java:891) at com.atlassian.jira.bc.projectroles.DefaultProjectRoleService.updateActorsToProjectRole(DefaultProjectRoleService.java:715) at com.atlassian.jira.bc.projectroles.DefaultProjectRoleService.addActorsToProjectRole(DefaultProjectRoleService.java:1073) at Script96.run(Script96.groovy:56)

Did you initialize the error collection?

Like this:

def errorCollection = ErrorCollections.empty()

If you've already done that, try adding some debug output and share the output?

log.info "currentUser=$currentUser (${currentUser.getClass()})"
log.info "usersToAdd=$usersToAdd (${usersToAdd.getClass()})"
log.info "projectRoles=$projectRoles (${projectRoles.getClass()})"
log.info "projectKey=$projectKey (${projectKey.getClass()})"
log.info "userRoleActor=$userRoleActor (${userRoleActor.getClass()})"
