Stuck retrieving OData with Spoon PDI (Kettle)

Support

I followed the Automating Data Delivery using the OData Endpoint in ODK Central showcase.

I didn't find the way to parse the fields with json input object. I'm using PDI 9.4 and ODKCentral 1.5

Here's a preview of the tutoriial:

and what I get when trying to select the fields...

If I choose to preview the data at the json object it seems all data is in the right field (result)

but I can't figure out why I'm not able to parse them, any help would be very appreciated.
