Check this if json_decode returns null
If json_decode returns null is it because the database.json is not valid.
You can fix this by open the database.json file and search for "Washington University: Seattle, WA" and remove the comma at the end.

I hadn't updated the downloads yet. Those are now updated so no one should be getting that error anymore.
However, just for reference, "NULL is returned if the json cannot be decoded or if the encoded data is deeper than the recursion limit."
