"RecursionError: maximum recursion depth exceeded" from ssl.py: `super(SSLContext, SSLContext).options.__set__(self, value)`

I am using Python 3.6.5 on the following remote server setup:

Server: Windows 10

Python: 3.6.5

Requests: 2.18.4

Pentaho: 8.0

When I run request.get against URLs in the server's command prompt, it gets the JSON as expected:

>>> import requests
>>> response = requests.get(url, headers=headers)
>>> json = response.json()
>>> print(json)
{'d': {'results': [{'_ ... 

However when I run the same script in CPython for Pentaho 8.0, I get

RecursionError: maximum recursion depth exceeded

Full log:

authtoken = "Bearer eyJ..."

If gevent is installed, it needs to monkey-patch the python sockets to cooperate (see documentation or this github issue).

Therefore gevent.monkey.patch_all() is either missing or not called early enough.

# at the beginning of the script
import gevent.monkey
gevent.monkey.patch_all()

# all the other stuff below, like for example
import requests
