This was due to 2 features not having a geometry member as indicated in the error message. 
This is illegal in GeoJSON, but apparently legal in ESRIJSon. I've just pushed a fix to avoid this 
error message and return a feature without geometry.
With the current versions, you should still be able to process the dataset. Just those features 
will be skipped.
