Thank you for reaching out and for bringing this to our attention! This definitely sounds like strange behavior - I’m looking into it now with our team - as soon as I have more information, I’ll post here.
@dapitts08 it looks like the error is occurring because their is no content on the “Category” Collection Template page. I tested on a duplicate of your site and after adding an element to that Collection page template then it worked without any errors.
Please let me know if adding an element to the collection template page and then republishing the site resolves the issue! Thanks in advance!
