Unable to fork a project on 11.10.4

Hi,

I have installed gitlab (version 11.10.4) from source on fresh Debian 9 Stretch host. During the installation evething went smooth. I created a new GIT project with a few files and when I trierd to fork the project, the UI hangs up. After refresh, I see the project is not forked and in the sidekiq.log I can see this Warning.

Does anybody encounter with the same issue?

Many thanks,
