Folder in Reposity can't be open in github

Question

I'm a new, after push project in repository I can't open the folder. how to fixed it ?

Answer 1

That symbol means that the google-auth directory is actually a submodule: a pointer to another git repository. You can't click on the link in github because it point at a repository that is not hosted on github.

In addition to the documentation I linked in the previous paragraph, there is also a Github blog on the topic of submodules.
