webresource client: TypeError: 'NoneType' object has no attribute '__getitem__

[czodrowskilab]

I just installed the web client into a new Conda env and ran this piece of code (taken from https://github.com/chembl/chembl_webresource_client):

from chembl_webresource_client.new_client import new_client
target = new_client.target
activity = new_client.activity
herg = target.search('herg')[0]
herg_activities = activity.filter(target_chembl_id=herg['target_chembl_id']).filter(standard_type="Ki")

Based on the issue referenced below:
pip install --force-reinstall gevent==1.2.2
pip install --force-reinstall greenlet==0.4.12

I'm ending up with this error message:
TypeError: 'NoneType' object has no attribute 'getitem'

Any clue what is going wrong?

Hi everyone, I have just been checking this in python 2.7 and the main issue are the updates to gevent and greenlet libraries, so I would suggest to execute the following pip commands:

pip install --force-reinstall gevent==1.2.2
pip install --force-reinstall greenlet==0.4.12

we just release a new version of the client dropping py2 compatibility and fixing any issue with py3.7.
