Git LFS problem

[LucasNova]

When I run build with script "game-target-build-pipeline" it throws next error on git clone stage:

batch request: git@github.com: Permission denied (publickey).: exit status 255

That's happen when it trying to download file via LFS. Some topics says that can be SSH or another authentication problem, but not any of possibly solutions from topics can't help. Did you have this problem? That's important because I think almost every Unreal Project uses LFS.

Looks like I found the workaround. Need add GIT_LFS_SKIP_SMUDGE=1 as Global Environment Variable in Jenkins, after that you need also add GitLFSPull to checkout extensions inside pipeline. It's very strange solution, but it works for me. I don't know how it will affect on projects without using LFS.
P.S. I can open pull request from branch lfs-fix, I think need some tests for any project without LFS usage. If you have that one, you can check it.
UPD: Also, I don't like to manipulate with global variable, I think it can be configured also inside pipeline for only one pipeline, not for all pipelines in Jenkins, but for other side LFS not working properly without it, and that global variable can't break any of them, I think.
