/.git/shallow.lock file exists error when deploy to Heroku

#1

Yesterday we had an error when application deployed to Heroku and the build process restarted. Since all build processes fail with the next message:

Warning: Permanently added the RSA host key for IP address '192.30.252.129' to the list of known hosts.
fatal: Unable to create '/home/ubuntu/reactor/.git/shallow.lock': File exists.
If no other git process is currently running, this probably means a
git process crashed in this repository earlier. Make sure no other git
[[ ! -s "$(git rev-parse --git-dir)/shallow" ]] || git fetch --unshallow returned exit code 128
process is running and remove the file manually to continue. Action failed: Fetch full repo

I’m trying to delete the shallow.lock via ssh, but the problem persists. How we resolve that?

Thank you for the help!
