問題

When trying to change the JIRA project lead from the Project Users and Roles settings, nothing happens after clicking on the update button, the Edit Project Lead window does not close and remain as is. 

• There are no errors in the JIRA logs.
• There are no abnormal behavior observed in the web request in the HAR file.
• Enabling Safe Mode does not change the issue behavior.

原因

This issue occurs if there is any invalid fields in the project's details: e.g. An invalid Project URL, a project key that exceeds the limit etc. 

It seems that JIRA is trying to validate the fields from the project's details before the Project Lead can be updated.

A similar bug has been reported under  JRA-61388 - Getting issue details... STATUS

ソリューション

Verify that all the fields in the project's details page has a valid content before updating the project lead.
