Expected behavior

This should be fixed in the latest extension version 0.4.44.

 az extension update --name aks-preview

Please report back if that fixes the issue.

I’ve got this

az aks enable-addons -a monitoring  -g gleb-aks-mangrove-fox -n gleb-aks-mangrove-fox
The behavior of this command has been altered by the following extension: aks-preview
The request content was invalid and could not be deserialized: 'Could not find member 'template' on object of type 'DeploymentDefinition'. Path 'template', line 1, position 12.'.

Fixed in extensions 0.4.60.

The issue below happens when using CLI 2.10.0 so make sure you’re on extension 0.4.60 or above if you plan to use latest cli and work with the monitoring addon.

Getting same error with aks-preview extension 0.4.58 using monitoring addon. Works without aks-preview extension
The request content was invalid and could not be deserialized: 'Could not find member 'template' on object of type 'DeploymentDefinition'. Path 'template', line 1, position 12.'.

Using CLI 2.4.0 cannot create AKS with windows node VM. Command: az aks create --resource-group myResourceGroup1 --name testSCluster1 --node-count 1 monitoring–enable-addons --kubernetes-version 1.17.3 --gener ate-ssh-keys --windows-admin-username azureuser --vm-set-type VirtualMachineScaleSets --node-vm-size Standard_F2s_v2 --network-plugin azure Error: The request content was invalid and could not be deserialized: ‘Could not find member ‘template’ on object of type ‘DeploymentDefinition’. Path ‘template’, line 1, position 12.’.

CLI2.1.0/2.2.0 can deploy it successfully.
