I am trying to create an approval history report and have followed the basic instructions in this post: Create approval history report with object fields?

I am now onto getting the information from an approval process instance and am stuck because I cannot get the instance to create any NewWorkItems. I have followed the process found here: https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_process_example.htm

I have also noticed that my getActorIds() returns null and the getInstanceStatus() returns Approved which it absolutely should not.
Any ideas on why this is happening would be greatly appreciated.

Apex Class:

global class GetQuoteAndApprovalProcessIds {
@InvocableMethod(label='Get Quote And Approval Ids')
global static List<Id> getIds(List<Id> quoteIdList){
    Id quoteId = quoteIdList[0];
    System.debug('!!!!!!quoteId!!!!!' + quoteId);
    List<Id> quoteAndApprovalProcessIds = new List<Id>();
    Id actorId;
    Id originalActorId;
    Id processInstanceId;

    ProcessInstance instance = [SELECT Id FROM ProcessInstance WHERE TargetObjectId =: quoteId Limit 1];
    System.debug('!!!!!!instance.Id!!!!!' + instance.Id);

    ProcessInstance step = [SELECT CompletedDate, CreatedById, CreatedDate,Id,IsDeleted,LastActorId,LastModifiedById,LastModifiedDate,
                                ProcessDefinitionId,Status,SubmittedById,SystemModstamp,TargetObjectId, (SELECT ID, ProcessNodeId, StepStatus,
                                                                                                         Comments,TargetObjectId,ActorId,CreatedById,
                                                                                                         IsDeleted,IsPending,OriginalActorId,ProcessInstanceId,
                                                                                                         RemindersSent,CreatedDate 
                                                                                                         FROM StepsAndWorkitems ) 
                                FROM ProcessInstance WHERE ProcessInstance.Id =: instance.Id];
    System.debug('!!!!!!ProcessInstanceStep!!!!!' + step);
    return quoteAndApprovalProcessIds;
}   

global class QuoteAndApprovalIdResults {
