From above error, seems unable to parse the memory of instance type Standard_M8-4ms, which is a decimal, not an integer.

$ az vm list-skus --size Standard_M8-4ms  --location southcentralus | jq -r '.[].capabilities[] | select(.name=="MemoryGB")'
{
  "name": "MemoryGB",
  "value": "218.75"
}

4.17.0-0.nightly-2024-09-16-082730

 Always

    1. set controlPlane type as Standard_M8-4ms in install-config
    2. create cluster
    3.
