Unable to deploy using deploy.sh

[mannuscript]

/kind bug

What steps did you take and what happened:
I am trying to deploy katib on minikube using deploy.sh provided in the examples. But there seems to be a problem:

> ./deploy.sh
+ set -e
+ minikube start --disk-size 50g --memory 4096 --cpus 4
😄  minikube v1.4.0 on Darwin 10.13.6
💡  Tip: Use 'minikube start -p <name>' to create a new cluster, or 'minikube delete' to delete this one.

Anything else you would like to add:
But it works when I change the api version to stable one:
