Null pointer exception when property value is null or empty object in GeoJSON file #22

Open dlutz2 opened 4 years ago

dlutz2 commented 4 years ago

The plugin throws a null pointer error when it encounters a GeoJSON property which is null or an empty object:

"properties": {
  "property": null
}

or

"properties": {
  "property": {}
}

The exception as seen in the Kettle log:

Using Kettle 8.3.0.0-371 and GIS Plugin V1.3.0

Looked at this further, the null pointer exception will also occur if a property is an array or a (not-null) object
