How solve issue TypeError: strings.slice(...).reduce is not a function?

Question

I recently dicovered Gatsby and I want to use this template for my own website: https://github.com/toboko/gatsby-starter-fine

When downloading it, manage to run it http://localhost:8000/ but I get this error which I can escape:

TypeError: strings.slice(...).reduce is not a function

I added my repository here so you can take a look too: https://github.com/melariza/gatsby-starter-fine

Could you take a look and help fix it?
