Hi, first thanks for wonderful plugin.
I am trying to import a Geojson file to grasshoppr. I used EsriJson component and connect the file path to it and make the boolean true.
I got this error : 1. Solution exception:Object reference not set to an instance of an object.
is there anything that I should do before connecting the file to the component ? How can I solve this? would be appreciated if you can help
