UPDATE: This was a temporary issue last a couple of days.
I developed a python apple news api client and I successfully pushed articles to preview in my apple news channel. Anyway, when I check the state of those articles, most of them is FAILED_PROCESSING. Only one went LIVE but without images (animated GIFs).
There aren't details about the error and I can't guess what is wrong. Articles look good in News Preview tool. Does anyone have any clue about? Any way to debug the issue?
Thanks!

>>>articles = client.search_articles()

Since you suggest that processing proceeded for articles not containing images, possibly your problem is related to not using bundled images.
