Health Probe Missing

[joschirm]

When you use the "Rolling" setting for the UpgradePolicy, you need to specify a Health Probe for the Scale set. This is not configured in the example:

"error": {
"code": "BadRequest",
"message": "Rolling Upgrade mode is not supported for this Virtual Machine Scale Set because a health probe or health extension was not provided."

Looking at this article:
https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/virtual-machine-scale-sets-automatic-upgrade#configuring-a-custom-load-balancer-probe-as-application-health-probe-on-a-scale-set

And adding the health probe with the same syntax as there, I still have an error:
"error": {
"details": [],
"code": "NetworkingInternalOperationError",
"message": "An error occurred."
