This project is a quick win for someone who knows and uses Gatsby.

I need someone to look at a blog that someone has been working on for their first portfolio. She has managed to get static pages running and a blog index roll but is struggling to get the pages working on click.

She was following this

and this (but I am told it was old package and had to be updated)
https://github.com/perkinsjr/gatsby-crash-course

She ended up with this, and as you can see it breaks when you click the title links for the blog.

I have given her a repo on my own GitHub so you can see the code and the commit history if it helps.

This person doesn't want help finish the website, they really want to complete their first project but are stuck. I have been asked to help get the blog pages to show up but I really don't want to spend my Sunday learning another static site generator, so $40 if someone can get the pages to render on clicking the blog titles.
