We have started to see false negatives when calling rest user permission search where the query is the accountId.
The response of this query is an empty list when it should return the user with account id 557058%3Aa8d85d49-2566-47f4-9f31-861930631857
Sometime yesterday the rest started to work returning the user in the response. Then it started to fail again today.
I'm trying the url and it seems like Atlassian has added accountId parameter? Now this one works
The account id param for user permission search is still not documented. Is this official?
