Observe:copy from a remote, the remote is a gerrit repository with GIT LFS

I have a Gerrit repository with GIT LFS, now i want synchronize it at Phabricator as “Observe:copy from a remote”. I only get the metadata of the GIT LFS files, how can i get the real file?

Phabricator duffision as follow

My Phabricator server configuration as follow

  1. Diffusion URIs:
    Observe:copy from a remote, the remote is a gerrit repository with GIT LFS
  2. diffusion.allow-git-lfs=true
  3. install git-lfs at the host, as follow:
    4bb49b69f25d:~ # git lfs version
    git-lfs/2.8.0 (GitHub; linux amd64; go 1.12.7; git 30af66bb)
  4. add /usr/local/bin/git-lfs to sudoers
    git ALL=(root) SETENV: NOPASSWD: /usr/bin/git, /usr/local/bin/git-lfs, /usr/bin/git-upload-pack, /usr/bin/git-receive-pack, /usr/bin/hg, /usr/bin/svnserve

I create a duffision at Phabricator with GIT LFS, it works good.

My Gerrit repositoy with GIT LFS also works good.
