My News Preview app returns an error on loading any article. The error message is "This document couldn't be opened. For details, see the error console...". When opening the error console it's completely empty.
I used the sample articles from https://developer.apple.com/documentation/apple_news/apple_news_format
Is there any way to debug this problem?
