在git协议下，当commit里面有lfs时，可以push， 但是pr会报错

[junwchina]

➜ git-repo-lfs-test git:(master) git pr
Uploading LFS objects: 0% (0/1), 0 B | 0 B/s, done.
batch request: invalid character '0' after top-level value
error: failed to push some refs to 'codeup.aliyun.com:606bafcd32fceefde379cc0e/git-repo-lfs-test.git'

---

[FAILED] ./ master (upload failed: exit status 1)

如果是https协议就可以正常pr。

使用 git pr -vv 能够复现，应该是 git-lfs 在 SSH 协议认证和推送上的问题。我们团队开发 git-lfs 服务端特性的同学会帮助看下。

$ GIT_TRACE=1 GIT_TRACE_PACKET=1 git pr -vv

服务端ssh解析AGIT_FLOW环境变量时有bug，测试后会在下周发布窗口发布，在这之前请使用 http 协议

经验证昨天的发布已经解决此问题。感谢 @junwchina 的报告。
