On git push I got error: error: invalid protocol: wanted 'old new ref'

Question

I have branch x. I type git push origin x:y

I got error message

error: error: invalid protocol: wanted 'old new ref'
fatal: internal server error
fatal: The remote end hung up unexpectedly
Counting objects: 140, done.

Maybe it is imporant: when I cloned repository, for performance I used switches

-b master --single-branch

git version 2.6.2.windows.1

gerrit version 2.9.4

Answer 1

When I decided to final investigation of the issue, it revealed that

git fetch --unshallow

solves the problem.

(Solves means allows push a branch, not push branch with shallow clone)
