Getting "Oops, something went wrong" error when trying to follow Tutorial


I’m currently just simply trying to follow the instructions in Create a Frontity Project - Frontity Tutorial to simply follow the demo. Unfortunately, I’m running into the error I mentioned in my title. Here’s a screenshot of the message and my console:

It just says I have an “internal server error” and I’m not sure what could be causing it.

It looks like a few other people have ran into this recently: Oops, something went wrong - #3 by eng.aminld. Could this be something new that’s broken?
