Group Picker will display an error on Create Screen Pop-up

A freshly-created Group Picker will display an error on Create Screen (pop-up) regardless the field is added to the project or not.

Steps to Reproduce

1. Create a Group Picker with the following configuration and make sure to return a Group object as intended by the feature:
   
2. Script:

    
   import com.atlassian.jira.component.ComponentAccessor 
   import com.atlassian.crowd.embedded.api.Group
   
   def groupManager = ComponentAccessor.groupManager
   def group = groupManager.getGroup("jira-developers") as Group
   
   return group ?: null
   

3. Click the Create button to create an issue (make sure it is the pop-up Create Screen).
4. Simply create an issue and that should trigger the error.

Expected Behaviour

Expect the issue to create properly without the error on the Create Screen.

Actual Behaviour

Workaround

Setting the Group Picker's Searcher to Group Picker Searcher will make it work. By default, it is set to none.

Additional Info

• Despite the error, the issue gets created in the backend and the Group Picker show the value correctly on Issue View.
• Tested some environment, below is the result:

  Jira version	ScriptRunner version	Issue occur?
  8.13.2	6.40.1	No
  8.20.0	6.40.1	Yes
