Topic says it all. I have registered to receive the attachment_viewed webhook in Confluence Cloud and I never receive the webhook. All of the other webhooks seem to work though. I have tried viewing the attachment as part of the page (image), viewing the attachment using the File preview (PDF) and downloading the attachment from the attachments screen. I never receive the event.
I have verified that the url is not being requested via server logs so it’s not a routing issue. I have double and triple checked the event spelling. Relevant snippet from my atlassian-connect.json is below. All hooks seem to fire except the attachment_viewed event.
