Paths in Gatsby site assume root of domain

[djones6]

If you fork Kitura.io and build the Gatsby site into your gh_pages branch, then try to use Github Pages to serve it on the default domain (yourname.github.io/kitura.io/), the links are broken.

They assume everything is being served from the root of the domain - for example, /learn instead of /kitura.io/learn.

This will work while a dedicated domain is associated to the site, but makes testing difficult.
