Script runner reading cascading field

[RamamandA]

Hi,

I am trying to create a script runner listener to read from cascading select field. I am using Jira 6.2.7 and Script runner 2.1.17. I have created a test project (TP) with field name "Cascading Select" and used example provided in this link https://studio.plugins.atlassian.com/browse/GRV-42

However I am getting below error when I run the script in script console. Any idea what is wrong in my case?

Thanks for your help!!

Here is the my script

import com.atlassian.jira.ComponentManager

import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.customfields.view.CustomFieldParams
import com.atlassian.jira.issue.fields.CustomField


ComponentManager componentManager = ComponentManager.getInstance()
CustomFieldManager customFieldManager = componentManager.getCustomFieldManager()

MutableIssue issue = componentManager.getIssueManager().getIssueObject('TP-7')
CustomField cf = customFieldManager.getCustomFieldObjectByName("Cascading Select")
CustomFieldParams cfVal = issue.getCustomFieldValue(cf) as CustomFieldParams

if (cfVal) {
Collection values = cfVal.getAllValues()
String first = values[0]
String second = values[1]

log.debug("First - second: $first - $second")
}
else {
log.debug("Custom field not present on this issue")
}

Here is the error

I've updated the example code in that issue to make it work on 6.x:
