Hi @steevej,
Thanks for the response, and @Jack_Woehr thanks for tagging him.
I don’t think the issue is related to Mongoose at all, since Error clearly say it’s MongoServerError. Also, I don’t want do it without a transaction because I am tracking unique user views, so it could happen that ArticleView will be created and later it would fail to increase the article’s view count, which would lead to data inconsistency. Thank you for the answer though.
