Superbedge error:invalid dataflowID while trying to update Dataflow. Has anyone faced such issue?

Hi there,
According to our trailhead module, we can get picklist value by Object Name and Field Name.
Trailhead Module (https://trailhead.salesforce.com/en/content/learn/projects/workshop-override-standard-action/override_2)

@AuraEnabled        
public static List<String> getPickListValuesIntoList(String objectType, String selectedField){
    List<String> pickListValuesList = new List<String>();
    Schema.SObjectType convertToObj = Schema.getGlobalDescribe().get(objectType);
    Schema.DescribeSObjectResult res = convertToObj.getDescribe();
    Schema.DescribeFieldResult fieldResult = res.fields.getMap().get(selectedField).getDescribe();
    List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
    for( Schema.PicklistEntry pickListVal : ple){
        pickListValuesList.add(pickListVal.getLabel());
    }     
    return pickListValuesList;
}

I want to add RecordTypeId to that method.
Any good idea for that?
Thank in advance.
