I would like to call the features drawn on my own in the OpenLayers map and export them in the .geoJSON format.

So far everything is working apart from the "Properties" section, which keeps coming with nothing, as you see below.

I would like to define something for every individual drawing I make on the map.

I found some nice approaches here:

Openlayers 3 draw set name

but it doesn't work in my code:

 var lineInteraction = new ol.interaction.Draw({ type: 'LineString', source: vectorLayer.getSource() }); lineInteraction.setActive(false); lineInteraction.on('drawend', onDrawend) { feature.setProperties({ 'id':1234, 'name': 'yourCustomName' }); console.log(feature, feature.getProperties()); }); 

Is it the OpenLayers library reason behind it? The aforementioned example refers to version 3.0.
