FeatureSet.save() to CSV - TypeError

[markegge]

I have a FeatureSet that I would like to save to CSV. One approach I've tried is to use the FeatureSet save() method. Unfortunately, attempting to save as a CSV produces a >> error. (Saving as a JSON file works just fine.)

Works (JSON)

In [14]: feature_set.save('data_folder', 'my_data.json')
Out [14]: 'data_folder/my_data.json'

Does not work (CSV)

In [15]: feature_set.save('data_folder', 'my_data.csv')
Out [15]: 
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

    693                 csv_writer.writerow(fields)
    694 

TypeError: string indices must be integers

Using Python 3.6, ArcGIS API for Python version 1.2.0.

For later versions, the FeatureSet supports SpatialDataFrames.

So if you do FeatureSet.df.to_csv(out_path) you can save the FeatureSet to a csv file.
