customfield_12471=Epic with name 'WGZMIG-1' is not unique


I'm trying to update a specific issue via SOAP:UpdateIssue method but I'm getting the following response :

com.atlassian.jira.rpc.exception.RemoteValidationException: Fields not valid for issue:
Errors: {customfield_12471=Epic with name 'WGZMIG-1' is not unique

I checked for duplicated values but I didn't find any. Could you please help me?

P.S: It's not applicable on all issues. I'm using GreenHopper 6.2.6.

Hey Rosy,

Judging by this message, it seems related to this KB to me.


Hey Tiago,

Thanks for your answer. However, I checked this KB before posting this problem. They suggested to upgrade GreenHopper to GreenHopper, or any latest version. My version is upgraded also, I checked for duplication using the suggested query:

SELECT * FROM jira521.jiraissue WHERE issuetype = (SELECT ID FROM issuetype WHERE pname ='Epic');

I didn't notice any duplication. What do you think?

Many thanks,


Can you additionally try if the there are duplicates in this query?

select stringvalue, count(*) count from customfieldvalue where customfield in (select id from customfield where cfname = 'Epic Name') group by stringvalue order by count asc;

Hello Renjith,

I didn't find any duplication using this query.

Thank you,
