Hi,
Until recently we were fetching the unassigned user avatar via this API request /secure/useravatar?size=xsmall&ownerId=undefined, but unfortunately this now returns a 404. Based on the documentation for the v2 REST API for Cloud, I could only assume that the way to fetch the user avatar for the unassigned user is to get the system avatars of type user - docs here.
The problem with this endpoint is that there is no indication of which of the returned avatars is the one for unassigned user - by manually checking them it looks like it’s the one with the ID of 10122.
My question is if the unassigned user avatar can be found at this ID in every Jira Cloud instance?
