问题
I have a Gatsby.js project that I host through Github Pages.
The project is within a directory called /an
I'm deploying it through gh-pages package with the following command
gatsby build --prefix-paths && gh-pages -d public -b master -e ./an
I've followed https://www.gatsbyjs.org/docs/path-prefix/ to set the proper prefix path. My custom 404 page is not detected through Github Pages. I believe it is because it has to be set on the repo root and not in /an.
How to tell GitHub Pages to use the 404 page generated in /an?
