Geocoding not working with ArcGIS Enterprise Portal

[jrmatchett]

Describe the bug The geocode function produces an error when using an Enterprise Portal GIS object. Geocoding works fine with an ArcGIS Online GIS object.

To Reproduce Steps to reproduce the behavior:

from arcgis import GIS
from arcgis.geocoding import geocode

gis = GIS('https://maps.myenterprise.org/portal', client_id='XXXX')

geocode('380 New York St, Redlands, CA 92373')

error:

Digging into this a bit further, the Geocoder's _address_field isn't getting set because a token isn't being generated when attempting to retrieve its properties (in this case, it's an Enterprise Portal geocoding service that isn't publicly accessible). The root cause appears to be what I pointed out in this issue with the Connection.generate_portal_server_token method not handing oauth authentication.

@jrmatchett thank you for this information, it's very helpful. I'll add it to our board and take a look at this.

The issue is resolved in v2.0.0 of the Python API, which will come out in Q1 of 2022
