Strange Error When Trying out Kubeflow via juju

I was just following this tutorials mentioned here:

As I was running the following command:

joesan@joesan-InfinityBook-S-14-v5:~$ juju add-model kubeflow
ERROR opening API connection: starting proxy for api connection: connecting k8s proxy: Get "": x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "")

As you can see that it fails and I’m clueless on how to get past this. The documentation does not mention anything about this. I’m sure that I’m missing something very simple. Could anyone please help me point out what this error could be and how to get past this?
