Hi, I'm trying to install periscope on a single nodepool, single node AKS cluster v1.15.7, but am experiencing the following error:

'The CustomResourceDefinition "diagnostics.aks-periscope.azure.github.com" is invalid: spec.versions: Invalid value: []apiextensions.CustomResourceDefinitionVersion{apiextensions.CustomResourceDefinitionVersion{Name:"v1"'

I'm running the latest Az CLI preview version.

$ az version
This command is in preview. It may be changed/removed in a future release.

$ az aks kollect -g k8s-demo-rg -n k8s-demo --storage-account stork8sdemo

This will deploy a daemon set to your cluster to collect logs and diagnostic information and save them to the storage account stork8sdemo as outlined in http://aka.ms/AKSPeriscope.

If you share access to that storage account to Azure support, you consent to the terms outlined in http://aka.ms/DiagConsent.

Do you confirm? (y/N): y
