How to properly post JSON data using Ajax to Flask

Question

When I log 'export_json' to the console prior to send the data via ajax the data is exactly the way I want it to be. It contains all the features I want. However, when I print the data to flask or write it to a JSON file the features are missing.The code I have shown here ends up writing nothing to the json file I've created but i've gotten it to write everything but the features before (e.g. what I said I had displayed in powershell down below). Does anyone know why the JSON object POSTed doesn't contain features? Please let me know if i'm not being descriptive enough!

Javsacript

    console.log(export_json)

    $.ajax({
        url: url,
        type: 'POST',
        dataType: 'json',
        contentType: 'application/json; charset=UTF-8',
        data: export_json,
        success: function(data){console.log(data)}
    });

Python

@app.route('/interactive', methods=['GET', 'POST', 'OPTIONS'])
def interactive():
    try:
        if request.method == 'POST':
            with open(output_json, 'w') as outfile:
                json.dump(request.get_json(force=True), outfile)

        resp = Response('whathaver')
        return resp
    except Exception, e:
        return (str(e))

if __name__ == '__main__':
    app.run(debug=True)

Here's what's displayed in Powershell:

{"displayFieldName":"","fieldAliases":{"FID":"FID","Name_1":"Name_1","LL_X_DD":"LL_X_DD","LL_Y_DD":"LL_Y_DD","Shape_Area
":"Shape_Area","PCT_LAND":"PCT_LAND"},"geometryType":"esriGeometryPolygon","spatialReference":{"wkid":4326,"latestWkid":
4326},"fields":[{"name":"FID","type":"esriFieldTypeOID","alias":"FID"},{"name":"Name_1","type":"esriFieldTypeString","al
ias":"Name_1","length":254},{"name":"LL_X_DD","type":"esriFieldTypeDouble","alias":"LL_X_DD"},{"name":"LL_Y_DD","type":"
esriFieldTypeDouble","alias":"LL_Y_DD"},{"name":"Shape_Area","type":"esriFieldTypeDouble","alias":"Shape_Area"},{"name":
"PCT_LAND","type":"esriFieldTypeInteger","alias":"PCT_LAND"}],"features":[]}

There should be features in "features" at the end there. Those features are present when I log 'export_json' to the console though but not present here. Any help would be greatly appreciated!

'export_json' how it appears in the console:
