This can occur when:
Performing a JIRA upgrade or restoration
A project is recently deleted
Diagnostic Steps
Run the SQL query below to verify if there are references to non-existent projects:
1
select * from nodeassociation where source_node_entity = 'Project' and source_node_id not in (select id from project);Cause
There are some non-existent project IDs in the nodeassocation table.
Solution
Resolution
Always back up your data before making any database modifications. If possible, test any alter, insert, update, or delete SQL commands on a staging server first.
To fix this, stop your JIRA instance and execute the delete SQL query below to remove the entries:
1
delete from nodeassociation where source_node_entity = 'Project' and source_node_id not in (select id from project);If you encounter this, please make a comment on the relating bug report:
