There's a set of ERROR logs in logstash related to Event-Platform extension and showing some bugs we have in the extension. Here I've categorised the errors by type:
- NPE on call to isDeleted() in onArticleRevisionVisibilitySet hook.
- Unable to deliver page_restore event due to old_page_id being 0
- Unable to deliver revision_create event due to rev_parent_id being 0
This is not a big problem, because these log entries are quire rare, but it would be nice to fix that.
