Getting 500 Error when trying to move issue from project to another

[Irshad Sheik]

When trying to move an issue to another project, we receive a 500 error page, ive gone thru the audit logs to see whats changed, the only changes that correlate with when the issue started is that of a screen change, ie, on a screen, a tab was removed, a new tab was added, since then ive re-added the tab that was removed and added the fields that were configured for that tab.

ive done a few lock re-indexes.

Hello,

Kindly check that the issue, you are trying to move, does not have sub tasks. If it does have subtasks, then move the subtasks too.

Good day

thanks for getting n touch., there are no sub tasks to the issue.

Hi Alexey 

Please may you advise if the Enhancer Plugin for JIRA may be the cause of this?

as currently the add-on is up for renewal. Projects contain custom fields which I believe may be the cause of the issue as the Enhancer Plugin for JIRA add-on is not active. 

I'm picking up this item where Irshad left it.
