How to recover admin role deletion

I did a very stupid thing.

I logged out of Fess after I erroneously deleted the admin role.
It is troubled that i can not enter the management screen even after logging in as admin afterwards.
Please let me know how I can recover, if there is a way.

Fess version is 11.3 on CentOS7.


See #921

It works.
But i succeeded to post on localhost:9200.
its correct?
