Null Pointer Exception When Trying To Delete Issue

I have migrated a JIRA instance to a new server. In this regard, I want to delete certain issues, which we don't need anymore. However, it returned an error with the following Message.

There might be a sub-task linked to the issue that doesn't exist/ is not visible, as there is a note that sub-tasks exists which will be also deleted. Any ideas? Thanks in advance!
