Diagnosis

Run the following SQL query to determine if you are affected by this issue:

select * from issuetypescreenschemeentity where issuetype not in (select id from issuetype);

If you are affected, this should return a results, else if there are no results from the above query, then you are not affected by this issue.

Cause

The issue occurs because there are issue types referenced in the issuetypescreenschemeentity table, however, they do not exist in the issuetype table.

Resolution

1. Shut down Jira

2. Run the following query to delete entries in the issuetypescreenschemeentity table that are invalid as they reference deleted/removed issue types.

   delete from issuetypescreenschemeentity where issuetype not in (select id from issuetype);

   Always back up your data before performing any modifications to the database. If possible, test any alter, insert, update, or delete SQL commands on a staging server first.

3. Start back Jira and verify if the issue persists
