Jira Sync Data Hygiene Error - Invalid value: Two values with same label (JiraValue) but different IDs found in the "FieldName" field of your project. Please update one of the duplicate values in Jira before attempting another sync.

Problem

Even though Jira integration sync shows as completed when checking the sync status, there is an error of Invalid value: Two values with same label (JiraValue) but different IDs found in the "FieldName" field of your project. Please update one of the duplicate values in Jira before attempting another sync.

This is a data hygiene issue in Jira. This error appears when a Jira field has 2 or more values with the same name.

So far, we see that this is what triggers it:

Given a single Jira project
and in any given field
when 2 values have the same label, that is, say Fix Version has 2 values of:
- 2.1
- 2.1

.
Couple of Other scenarios which can result in the issue:

Issue Type field has 2 values - To Do and a second To Do in the same project.
User field with different user emails but the same full name
- email: nicholas.doe@company.com, Full Name: Nick Doe
- email: ndoe, Full Name: Nick Doe

Solution

Jira Account Admin will need to use the message to identify the field and value that requires clean-up. They will need to edit the value name to be unique from any other value in that specific field.

Please note that if the error refers to a user field, the full name and public name need to be changed i.e. Nick Doe can be changed to Nick Doe Old.
