I confirm, I also beginning to get “404” for users who are not returned by the endpoint /users".
I need to query specific users when I loop my task history (stories), and I find 1 story to 1 user that is not on the list received with the “/users”.
It always worked, but since a few days I get 404 for these users.
But, if I query stories and I add opt_fields values for created_by, I see the in formation I need.
Only their email is now null to not allow me to contact them I think it’s ok.
But, I don’t want to add these opt_fields when I query actions, I only need the creator “gid”, and then for unknown, I will query for these users 1 by one, only once, that allows to do smaller and faster api queries.
I think asana should remove that new validation and let us query for these old users that are listed in “stories” or anywhere else in the data.
