(...)Cause
There are issues in the imported project which are included in Sprints that do not exist in the database anymore (in the AO_60DB71_SPRINT table).
JSWSERVER-16064 - JIRA should Check if Tickets are Referencing a Sprint that does not Exist
Investigation
Run the following query in the source instance's database (the Jira Software instance where the XML Backup was taken) to find the affected entries:
ℹ️The queries below were tested for PostgreSQL and MySQL, you would need to find the corresponding query for your database type
Query 2 (PostgreSQL)

-- List all references to the nonexistent Sprints
SELECT * FROM customfieldvalue
WHERE customfield = (SELECT ID FROM customfield WHERE customfieldtypekey LIKE '%com.pyxis.greenhopper.jira:gh-sprint%')
AND CAST(stringvalue as int) NOT IN (SELECT "ID" FROM "AO_60DB71_SPRINT");

AND stringvalue NOT IN (SELECT ID FROM AO_60DB71_SPRINT);
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.
Stop your Jira Software source instance.
Run the SQL query below in the database to delete the invalid Sprint references:
Query 3 (PostgreSQL)

1 2 3DELETE FROM customfieldvalue WHERE customfield = (SELECT ID FROM customfield WHERE customfieldtypekey LIKE '%com.pyxis.greenhopper.jira:gh-sprint%') AND stringvalue NOT IN (SELECT ID FROM AO_60DB71_SPRINT);Start your Jira Software source instance.
Generate a new XML Backup from the source instance and perform the Project Import in the target instance again.
