Bug: properties.count is missing when creating auto scaling agent pool

[b1zzu]

Version of Azure Service Operator mcr.microsoft.com/k8s/azureserviceoperator:v2.2.0

Describe the bug I'm trying to create the following managed cluster agent pool:

apiVersion: containerservice.azure.com/v1api20230201
kind: ManagedClustersAgentPool
metadata:
  name: highmem
  namespace: default
  annotations:
    serviceoperator.azure.com/reconcile-policy: detach-on-delete
spec:
  azureName: highmem0
  owner:
    name: my-cluster
  mode: User
  enableAutoScaling: true
  minCount: 3
  maxCount: 21
  upgradeSettings:
    maxSurge: 33%
  vmSize: Standard_E2s_v4

but the reconciliation loops fails with the following error:

Workaround

Add count: 1 to the spec, it will be ignored because the auto-scaling settings will overwrite it but at least will fix the issue.
