Howdy everyone,
Just wanted to keep everyone updated. I have tested this issue and have hit the same error that seems to be occurring. I have entered a Jira report for this issue so that it may be resolved in a future release. if you have any more questions regarding this issue, please refer to that AnswerHub post so that I may be able to further investigate. I am unsure as to a certain time frame of when this will be implemented. I will be sure to keep you all updated.
