Minikube MountVolume failed for volume "config-volume" - kubernetes

Question

I'm facing an issue with my ubuntu:16.04 desktop, using minikube version: v0.35.0, kubectl both client/server: 1.13.4
When I try running a configmap example and get error kubelet, minikube MountVolume.SetUp failed every time I try. I tried to debug but no result on my end. It's about last 2 days and failed to make it work.
$ kubectl apply -f ./kube-pod.yml
apiVersion: v1
kind: Pod
metadata:
name: kuard-config
spec:
containers:
- name: test-container
image: gcr.io/kuar-demo/kuard-amd64:1
imagePullPolicy: Always
command:
- "/kuard"
- "$(EXTRA_PARAM)"
env:
- name: ANOTHER_PARAM
valueFrom:
configMapKeyRef:
name: my-config
key: another-param
- name: EXTRA_PARAM
valueFrom:
configMapKeyRef:

key: extra-param
volumeMounts:
- name: config-volume
mountPath: "/config"
volumes:
- name: config-volume
configMap:
name: my-config
restartPolicy: Never
Giving the following error when I run the following command
$ kubectl describe pods/kuard-config

I'd expect if someone help me to figure out why `kubelet, minikube MountVolume.SetUp failed` is occur.
