Error parsing json from demo2 to heart

[dada1smo]

Hey, everyone.

I'm trying to implement the demo on a Gatsby project. I've decide to take the shortcut of importing the full scripts instead of converting everything to React. Some things run okay, but I seem to be getting an specific error when parsing the JSON from demo2 to heart.

This error keeps showing up in different ways, and I don't quite understand why, since I've kept the JSON pretty much the same.

Has anybody encountered a similar problem with JSON parsing?
