Google App Engine (python) - Connecting to local datastore via python script

Question

I've been able to connect from a local script directly to the Google App Engine (GAE) ndb store on the server as described in this article .

But I'm trying to do the same thing to access my local dev server but am not able to. My dev API server runs at http://localhost:42020 but when I try to connect using the following command:

$ remote_api_shell.py -s http://localhost:42020

I get the following error:

Traceback (most recent call last):

Is it not possible to connect locally?

Looks like I was doing it wrong. This answer solved my problem.

In short, I had to connect to the regular web server for it to work without the leading http. This asks for my email and password and once I enter that, it works!

$ remote_api_shell.py -s localhost:8080
