Test Notes

Try running this custom workflow on a form before applying the PR & then verify it then works as expected with PR applied

public class ReplaceValuesWorkflow : WorkflowType
{
    public ReplaceValuesWorkflow()
    {
        Id = new Guid("864ffbe8-b4ab-4a09-8cc5-49084918d63a");
        Name = "Replace all Values";
        Description = "Replaces all open fields beside question id with Anonymized";
    }
        
    public override WorkflowExecutionStatus Execute(Record record, RecordEventArgs e)
    {
        //Due to data legislation, we have to delete the personal fields from the current form. 
        using (var store = new RecordStorage())
        {

            var records = store.GetAllRecords(e.Form);

            foreach (var rec in records)
            {
                foreach (RecordField rf in rec.RecordFields.Values)
                {
                    if (rf.Alias != "questionid" && rf.Values.Any())
                    {
                        rf.Values[0] = "Anonymized";
                    }
                }
                store.UpdateRecord(rec, e.Form);
            }
        }

        return WorkflowExecutionStatus.Completed;
    }


    public override List<Exception> ValidateSettings()
    {
        List<Exception> exceptions = new List<Exception>();
        return exceptions;
    }
}

It works :) Merged in both for v4 and v6
