push changes to a GitLab repo returns 411 error

Does anyone encounter that push change to a gitlab repo and returns "Request failed with status code: 411" error?

I hava a reference #905 comment on GitHub, but still getting the same error when debugging it gets to git_remote_push which returns res = -1 and Ensure.ZeroResult(res) returns 411 error.

In addition, we are running gitlab (v8.8.2) on our own server. Use the Libgit2sharp version 0.24.0.0

首先，使用 Libgit2sharp 0.24.0.0 重現針對所回報的 self-hosted GitLab 8.8.2 設定執行 push 的過程，然後透過 git_remote_push 和 Ensure.ZeroResult(res) 追蹤失敗原因，並以參考 #905 作為內容背景。完成的標準是找出 push 產生 HTTP 411 的原因，並記錄或測試一個已確認的解決方案。
