[silaspath]

In the extension schema, the following key-value pair is invalid:
"type": "extensions"

However, the below works:
"type": "Microsoft.Compute/Extensions"

Turns out that's incorrect as well.

I copied a schema from template of a current Windows VM with the extension installed post-deploy:

        {
            "type": "Microsoft.Compute/virtualMachines/Extensions",
            "apiVersion": "2019-07-01",
            "name": "AzureNetworkWatcherExtension",
            "location": "[resourceGroup().location]",
            "dependsOn": [
                "[resourceId('Microsoft.Compute/virtualMachines', variables('vmName'))]"
            ],
            "properties": {
                "publisher": "Microsoft.Azure.NetworkWatcher",
                "type": "NetworkWatcherAgentWindows",
                "typeHandlerVersion": "1.4",
                "autoUpgradeMinorVersion": true
            }
        }

The below error appears:

Deployment template validation failed: 'The template resource 'AzureNetworkWatcherExtension' for type 'Microsoft.Compute/virtualMachines/Extensions' at line '238' and column '64' has incorrect segment lengths. A nested resource type must have identical number of segments as its resource name. A root resource type must have segment length one greater than its resource name. Please see https://aka.ms/arm-template/#resources for usage details.'. (Code: InvalidTemplate)

@damendo since your team works on Network Watcher, can you take a look at this?

[damendo]

@jaydarius the type is correct. But you need more segments in the name.
See: https://docs.microsoft.com/en-us/azure/azure-resource-manager/templates/child-resource-name-type#outside-parent-resource

Something like VmName/AzureNetworkWatcherExtension should work.
