...The error above is saying that a duplicate of object type attribute with ID 31706 is found and hence, export failed.
We can use the SQL query below to verify the issue in the database by returning a list of objects that has a duplicated attribute value for object type attribute with ID 31706. Example results are shown below.

(5 rows)Alternatively, we could use the built-in Insight health check tool to check for duplicated attribute values. The Insight health check tool can be accessed by any Jira admins on <Jira_base_URL>/secure/admin/InsightPluginHealthCheck.jspa.
Cause
Whenever an object is created, there is a record added to the database for every object type attribute if there's at least one value. There shouldn't be any record for any object type attribute that is without a value (null) or duplicated object type attribute as shown above.
The cause of the duplication is unknown.
Solution
The duplicated values can be deleted by clicking on the Delete duplicated values button available on the health check page. It's recommended to run an Insight clean re-index or Insight re-index after deleting the duplicated values.
Other Notes
The operation to check for duplicate values and to delete could cause Jira performance issue if the Jira instance is busy and with large amount of Insight objects. It's recommended to perform the operation(s) during non-peak hours.
