Fetch Online Data Example - Token Parsing Error

[horaciovelvetine]

Hello!

I use this library to grab details and data from Wikidata for an app I am developing for school and recently have come across an issue which I am completely stuck on. Cloning the toolkit and running the aforementioned example appears to throw an unexpected Token error from Jackson when trying to read/deserialize some data.

I attempted to dig into this issue to the best of my (very limited) knowledge and found mention of the REST API transition in this issue:
Wikidata-Toolkit/Wikidata-Toolkit#755 - and was wondering if there had been any related changes of late (last 2/3 months approximately) that may have broken the ability to pull data using this library.
