TypeError: Cannot read property 'access_token' of null

First, cleanup:

$ rm ~/.config/earthengine/credentials

Then run example script:

$ node ee-runner.js examples/hello.js

If browser does not open, use the following URL to get access code:
https://accounts.google.com/o/oauth2/auth?scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fearthengine.readonly&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&response_type=code&client_id=517222506229-vsmmajv00ul0bs7p89v5m89qs8eb9359.apps.googleusercontent.com

Please enter authorization code: 
[auth code]
Entered code: [auth code]

At this point the script stops and nothing happens until I press Enter, which gives this:

Entered code:

            ee.data.authToken_ = 'Bearer ' + tokens['access_token'];

The weird thing here is that the image does download this first time I run the script after clearing the credentials, despite the hangup and error. Running the script again only gives the error, no image is downloaded.

No credentials get written to the credentials file:

$ cat ~/.config/earthengine/credentials
{}

At least {} is fixed in the latest github version, but it still hangs using the above scenario - will investigate further
