extract_data sample

Question

* I have a Hosted Feature service that I own and also have the Extract capability enabled. * Contains two layers, of which I want to download the first layer into a file geodatabase I was hoping to find a sample that uses arcgis.extract_data This post is similar, but looks like the op ended up using ArcPy. Have tried a few things: from arcgis.gis import GIS from arcgis.features.manage_data import extract_data gis = GIS("https://mydevplan.maps.arcgis.com/","un","pw") waze_hfs_item = gis.content.get('5c80a03f09154b2bb845f986dce325cd') waze_alerts_layer = waze_hfs_item.layers[0] # REST Endpoint for layer returned # outputGDB = arcgis.extract_data(['Alerts']) # Exception: Job failed. # outputGDB = arcgis.extract_data(waze_hfs_item) # Exception: Job failed. outputGDB = arcgis.extract_data(waze_alerts_layer) # TypeError: 'FeatureLayer' object is not iterable‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I believe all I really need to supply to extract_data is : input_layers :Required list of strings Was wondering if someone could point me to a working sample that leverages extract_data. I am sure this is a simple one.

Using createreplica gets around the credits issue, but the service needs SYNC enabled (which has more overhead for publisher when compared to Extract). replica = waze_flc.replicas.create(replica_name = 'Waze_Download', layers = '0', data_format = 'filegdb', out_path = './download')‍‍‍‍

outputFGDB = extract_data(waze_hfs_item.layers, output_name="Waze_Extract", data_format="FILEGEODATABASE") outputFGDB.download('C:\Workings\waze_analysis')‍‍ The above works in downloading all of the layers from the hosted feature service to a shapefile. * I only want the first layer. How can I achieve this? waze_hfs_item.layers[0] throws an error. * Has anyone created a clean-up step to remove the new item from the portal after successfully downloading? If I refer to the credits page: What does not require service credits? * Exporting data stored in ArcGIS Online. However, I can confirm that using extract_data does indeed use credits. Is this a bug? As we are doing this on a daily basis, using credits for exporting our data is not going to be feasible. Was hoping to take the Extract path over using SYNC/CreateReplica.
