Notes
If you want to check only the affected users first, you can use this:
select distinct um.username as "creator" from content c join user_mapping um on c.creator = um.user_key where c.contenttype = 'DRAFT' and c.draftspacekey not in (SELECT spacekey FROM SPACES) order by um.username;
Workaround
- Find all drafts connected to non-existing spaces in the database:
select c.contentid, c.title, c.draftspacekey, um.username as "creator" from content c join user_mapping um on c.creator = um.user_key where c.contenttype = 'DRAFT' and c.draftspacekey not in (SELECT spacekey FROM SPACES) order by c.creator;
- For every response, log in as the 'creator' and access this (won't work if you log in as any user other than the creator):
https://instance.atlassian.net/wiki/json/deletedraft.action?draftId=<draft_id>&atl_token=#form_xsrfToken()
- Replace the '<draft_id>' for the 'contentid'.
- If it works, that line should no longer appear in the select above and this should be shown in the page:
