Python: ValueError("Invalid value for `match_expressions`, must not be `None`") when calling kubernetes.client.CoreV1Api().list_namespaced_pod

[liwandaniel]

When I try using the kubernetes.client.CoreV1Api().list_namespaced_pod method, I get the error:

  File "xxx/lib/python3.6/site-packages/kubernetes/client/models/v1_node_selector_term.py", line 49, in __init__
    self.match_expressions = match_expressions
  File "xxx/lib/python3.6/site-packages/kubernetes/client/models/v1_node_selector_term.py", line 72, in match_expressions
    raise ValueError("Invalid value for `match_expressions`, must not be `None`")
ValueError: Invalid value for `match_expressions`, must not be `None`

the way of calling method:

kubernetes.client.CoreV1Api().list_namespaced_pod(namespace="kube-system")

I'm just trying to list all pods for kube-system namespaces

I'm using Python 3.6 with Kubernetes 1.12.2 and kubernetes-client v5.0.0，and I've tried kubernetes-client v6.1.0
