urllib3.exceptions.ResponseNotChunked from watching namespaced configmap or secret

[JTarball]

What happened (please include outputs or screenshots):
The following api calls against CoreV1Api
list_namespaced_secret
list_namespaced_config_map

fail straight away with w.stream() if the resource version is added

raise ResponseNotChunked( urllib3.exceptions.ResponseNotChunked: Response is not chunked. Header 'transfer-encoding: chunked' is missing.
What you expected to happen:
Not fail straight away the below code works for list_namespaced_event etc

How to reproduce it (as minimally and precisely as possible):
`
w = watch.Watch()

    for event in w.stream(self.v1api.list_namespaced_config_map, namespace, resource_version=resource_version):

`

Anything else we need to know?:
resource version is definitely set to a string

• not adding the resource version kwarg makes the code work fine

Environment:

• Kubernetes version (kubectl version): Major:"1", Minor:"14", GitVersion:"v1.14.7",
• OS (e.g., MacOS 10.13.6): 10.15.1
• Python version (python --version): Python 3.8.1
• Python client version (pip list | grep kubernetes): 11.0.0b2

Could you share more code about how you extracted the resource version? Also could you enable the debug switch and share the API response?
