... 10 moreAfter reviewing the exception, we noticed that the getRelatedCommentVersions() method has been called. This method returns the comment versions for all comments associated with the specified parentIssueId. The comment versions are stored in the comment_version database table.
To check duplicate records in the *comment_version* table, go to the database query tool, and run the following SQL statement:
1
2
3
select cv.comment_id, cv.parent_issue_id, count(*)
from comment_version cv
group by cv.comment_id, cv.parent_issue_id having count(*) > 1;This query should return all comment IDs and their associated parent issue IDs as below:
1
2
3
4
5
comment_id | parent_issue_id | count
------------+-----------------+-------
958769 | 647038 | 2
958785 | 647038 | 2
(2 rows)Notice that the query output show duplicates, and the parent_issue_id matches the entity ID from the WARN message.
To see the duplicates, query the database by the comment_id:
1
select * from comment_version where comment_id in (958769,958785);The output will look like:
1
2
3
4
5
6
comment_id | parent_issue_id | update_time | index_version | deleted
