Error using python client

[Guy]

I'm trying out the python client library on CB 2.0 and have run into the following error, from a very simple script. At the moment all it does is just try to instantiate a couchbase connection object but fails.

Here's the code:

#!/usr/bin/env python

from couchbase.client import Couchbase

cb = Couchbase("<server ip>:8091", '<bucket_name>', '<bucket_password>')

The error I get:

Traceback (most recent call last):
  File "./testcb.py", line 7, in <module>
    cb = Couchbase("10.210.94.180:8091", 'app', 'm1n1wh34t5')
  File "/usr/local/lib/python2.6/dist-packages/couchbase/client.py", line 61, in __init__
    self.couch_api_base = config["nodes"][0].get("couchApiBase")
TypeError: 'NoneType' object is unsubscriptable

Does anyone have an idea what the problem is?

Thanks,
Guy

That's not expected.  What OS and specific version of Python do you have?

Oops, guess I need to check the error code for secure details before posting it! Anyway, here's the info you requested:

Python 2.6.5
Ubuntu Lucid (10.04)

I'm not sure that your test code is valid. Couchbase client expects "host:port", "username" and "password" parameters.

See this usage guide for details:

https://github.com/couchbase/couchbase-python-client

Particulary:

from couchbase import Couchbase

# connect to a couchbase server
cb = Couchbase('localhost:8091',
               username='Administrator',
               password='password')

# fetch a Bucket with subscript
default_bucket = cb['default']

This happens when you try to connect your server behind a proxy and "requests" python library receives 504 Gateway Timeout error, eventually your object "config" on line #61 in couchbase/client.py becomes a None.. 

Disable your proxy settings system-wide or add 2 lines below within your ~/.profile or ~/.bashrc file (by replacing necessary values of course):

export http_proxy="http://username:pass...@example.net:3128/"

export https_proxy="http://username:pass...@example.net:3128/"

hope that helps..
