Can't connect to Boron LTE

[TimAtFacture]

Trying to use this example as a tutorial for integrating my Particle devices with our custom website. I have a Boron LTE running firmware that's correctly handling Function and Variable requests from the Particle Console. I created an OAuth client from the Console, and entered the Client ID and Secret, but whenever I try reading any Variables or executing any Functions with the Spark-Helper I get an error message.

I realize this is a very old example, is there any reason to believe it's not still working?

I'm also posting a similar issue to the Particle Community

Sorry @TimAtFacture, I have not kept up with this repo or the technology for quite some time so I can't offer any help.
