I'm trying to access the files from my ArcGIS Notebook. I thought it would be helpful to develop in an IDE on my local system and write a little script to deploy all the file dependencies into /arcgis/home. 

I can connect to the GIS() via a saved profile, get the Item for my Notebook, get the list of tasks, etc., but I'm stuck on accessing the files. My understanding is that I'm supposed to create a NotebookServer object (arcgis.gis.nb.NotebookServer) and its data_access property returns an arcgis.gis.nb._dataaccess.NotebookDataAccess object. That has a files property and an upload() method which should be the rest of what I need.

Here's what I'm trying: 

base_agol_url = 'https://<MY_ORG>.maps.arcgis.com'
gis = GIS(profile='AGOL')
nb_server = NotebookServer(url=base_agol_url, gis=gis)
nb_da = nb_server.data_access
nb_da.files  # THIS LINE FAILS

After line 4, I have the nb_da variable, which is a NotebookDataAccess object and it has all the properties I'd expect. Line 5, however, returns a json.decoder.JSONDecodeError with a super lengthy Traceback (see below). To instantiate NotebookServer (line 3), you pass in a URL and a gis object. I assume the URL is the base URL for our AGOL instance, but the gis object has that URL embedded, so that seems redundant. I tried guessing at a few other URLs on line 3, including https://notebooksservices.arcgis.com/admin, but didn't make any progress. 

Does anyone have some sample code to create a NotebookDataAccess object with a valid set of files? I think once I get that going, I'll be off to the races. 

Here is the traceback from line 5 in the code snippet above:
