[GeoNode-users] ArcGIS Rest Remote Services

[Michael Fedak]

Hello,

I have been trying to add ArcGIS Rest resources to a deployment of 2.7.0.

I have not found any documentation on the use of this feature but have
managed to add a mapserver as well as a featureserver as remote services
but cannot import any resources. The interface displays the following
messages:

> no resources can be imported
>
and

> Cannot Parse Any Resource At This Time!
>
Stdout has the following message:

>
> Internal Server Error: /services/3/harvest
Traceback (most recent call last):

I am guessing that the issue is the arcrest python package that is being
used to harvest layers from the rest services. That package has been
superseded by the ArcGIS API for Python:
https://github.com/Esri/arcgis-python-api

I was wondering if anyone had attempted to replace the arcrest package with
the new API?
