Cannot Install Greenplum on Kubernetes

I'm trying to install Greenplum on Kubernetes v2.3.0 on minikube for a project. After installing the greenplum-operator I cannot install Greenplum cluster it shows the following error -

"Error from server (InternalError): error when creating "my-gp-instance.yml": Internal error occurred: failed calling webhook "greenplum.pivotal.io": Post "https://greenplum-validating-webhook-service-d59bbbb85-bjwhr.default.svc:443/validate?timeout=10s": x509: certificate relies on legacy Common Name field, use SANs or temporarily enable Common Name matching with GODEBUG=x509ignoreCN=0"

I tried to search for answers on VMware connect hub but their login portal is down since past 2 weeks. Another work around I tried is deleting the validatingwebhookconfiguration.admissionregistration.k8s.io that operator creates inside kubernetes cluster. GreenPlum Cluster is created but cannot start the postgres process within.

greenplum-operator logs:
