Build a React App Tutorial Fails with Error

Support
1

I have a StarDog server running on my M1 Mac, thanks to help from @matthewv.
I'm trying to learn how to access my StarDog server by following this React App tutorial.

However, it's failing with these errors:

node ~/stardog-react/src/data/load-data.js

Creating StarWarsDB...

}

What am I missing?
Thanks

Hi Jeroen,

this seems to be an issue caused by the stardog dependency. I think there is fetch related PR open in the stardog.js repository. This could solve your issue once it is merged.

Cheers
