Hello Jira-(Server/DC-)Users,
if you use
- Jira Server or Datacenter
and - REST-Calls obtaining user lists as results
you should double check your application after Jira Core Update, if it still works as intended.
IMHO updates to Version
- 8.20.7 or higher
- 9.0.0 or higher (from <=8.20.6)
does affect some REST api calls - and I couldn't find an entry in the REST API-Changelog (status 2022/07/27)!
According to my research at least the following endpoints are affected:
- /rest/api/2/user/assignable/search
- /rest/api/2/user/assignable/multiProjectSearch
- /rest/api/2/user/viewissue/search
In previous versions there was a Parameter startAt that allowed pagination, which has been dropped in the (minor) update!
In both, previous and current versions there is a Parameter maxResults, which limits the maximum result count in the reply - but in the new version it was hard limited to 100 (previous: 1000). IMHO you are only affected if you don't pass the parameter username some endpoints mentioned above have (in other words: if you expect list of users from the endpoint).
Problem: previously you could get up to 1000 users via this calls. After the update you silently only get 100 users at a maximum (higher values in maxResults are treated as '100') and startAt-Parameter is simply ignored now.
In the detailed changelog the 'Bugfix' which causes this problem does appear: JSWSERVER-21156
There also exists some feature requests regarding that problem: JRASERVER-71380, JRASERVER-73362
If Jira DC supports REST API V3, the problem may be also solved: Feature-Request JRASERVER-70688
