I am trying to use kubernetes python client to execute a script inside, say podA from another pod, say podB, using the connect_get_namespaced_pod_exec method. Which is throwing this error:
Traceback (most recent call last):

The kubernetes Server version is : 1.16, and I was using the latest version of kubernetes python api. I tried downgrading that to 12.0.0, the issue still persisted. Why am I getting this error? What should I try to fix it?
