Saerching point of interest not working for me :'(

Hello knime friends, I am working on a proyect that allows me to locate particular areas within a stipulated radius but for some reason “unknown to me” I cannot make it work. I would like to know where is the problem.

By the way (I found a stream on this topic “Geospatial Points of Interest Search Example” but I can’t get it to work in my country “Argentina”).

In my particular case I am trying to find Hospitals around a 5km radius from this latitude: -34.603610824843145 and this longitude: -58.38155967478099 . i think the CRS (Coordinate Reference System “WGS 84” ) for my country is not correct.
