unable to use locally hosted github installation

[tgourley01]

The info object has ghepurl property but it never gets populated. If I override it with our github host details I am able to get authorization tokens - info.ghepurl = "https://xxx/api/v3"; (note the api endpoint - ../api/v3)

Without overriding this value it sends your creds to github.com (which fails) (it sends to github.com even though the git repo url is pointing to a local github server)

I don't know the design well enough to make suggestions but it appears the code was at least partially designed with this in mind.
