How to hide certain values in a single select custom field on Jira service Desk customer portal?

[Deleted user]

Hello All,

We have Organized Jira Service desk Request Types to multiple Groups to appear in the customer portal Ex: Jira, Confluence, Bitbucket and Bamboo.

Each Group has multiple Request types For Example: Jira has following Request types New Account, modify Field, Edit Project, Reporting and Bug.
Group confluence has following Request types New Confluence Space, Additional functionality, Bug and Performance

For Groups Jira and confluence has following fields on Customer portal Summary, Description, Attachment and Servers. Servers custom field has following Options Server1, Server2, Server3 and Server4.

Now we want to Restrict the values on the Servers field depend on the Request Type group. Ex - If user selects a Group Jira and Request name Bug on the customer portal Servers field
has to show following options Server1 and Server2 and same way if user selects Confluence group and Request name Bug Servers field has to show only following options Server 2 and Server 3.

To achieve this we have added below script in the behavior and mapped to Jira service desk project and All Request Types. But script is not working it is showing error in the attached screen shot.

import com.atlassian.jira.issue.util.DefaultIssueChangeHolder
import com.atlassian.servicedesk.api.requesttype.RequestTypeService
import com.onresolve.scriptrunner.runner.customisers.WithPlugin
import com.opensymphony.workflow.WorkflowContext
import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.customfields.option.Option
import com.atlassian.servicedesk.api.requesttype.RequestType
import com.atlassian.jira.user.ApplicationUser

@WithPlugin("com.atlassian.servicedesk")

RequestTypeService requestTypeService = ComponentAccessor.getOSGiComponentInstanceOfType(RequestTypeService)
def currentUser = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
ApplicationUser user = ComponentAccessor.getUserManager().getUserByName(ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser().name)
RequestType getRequestType = requestTypeService.getRequestTypeForIssue(user, underlyingIssue).right().get()

def issueField = getFieldByName("Server")

def customFieldManager = ComponentAccessor.getCustomFieldManager()

String requestTypeName = getRequestType.getName()

def optionsManager = ComponentAccessor.getOptionsManager()

def customField = customFieldManager.getCustomFieldObject(issueField.fieldId)
def config = customField.getRelevantConfig(getIssueContext())

def options = [:]
def listOpt = ["Server1", "Server2"]
def listOpt1 = ["Server3", "Server4"]

if ("Jira".equals(requestTypeName)) {
options = optionsManager.getOptions(config).findAll{ it.value in listOpt }
issueField.setFieldOptions(options)
}
else {
options = optionsManager.getOptions(config).findAll{ it.value in listOpt1 }
issueField.setFieldOptions(options)
}

Thanks in advance,
