I want to download private rpository during setup of devcontainer but I'm asked for username and passwrod

I have credential helper set in .gitconfig. When I use "postCreateCommand":["bash", "-c", "git config -l"], I got following output:

Run in container: bash -c git config -l
filter.lfs.required=true
filter.lfs.clean=git-lfs clean -- %f
filter.lfs.smudge=git-lfs smudge -- %f
filter.lfs.process=git-lfs filter-process
credential.helper=!f() { /home/.vscode-server/bin/74b1f979648cc44d385a2286793c22

core.filemode=true

core.logallrefupdates=true

When I try to download private repo, I get ask about username, but when I delete postCreateCommand form devcontainer.json, and execute the same git pull command inside the container, it works right away, and do not ask me for password

Steps to Reproduce:

1. add postCreateCommand step to devcontainer that will pull private repository form github via https "postCreateCommand":["bash", "-c", "git clone https://url_to_private_repo"],
2. rebuild container
3. the container asks for username
