I want to create a metric alert rule and attach some existing action groups to that rule. My powershell code is showing some error like this

" Add-AzMetricAlertRule : Cannot bind parameter 'Action'. Cannot convert the    "Microsoft.Azure.Management.Monitor.Management.Models.ActivityLogAlertActionGroup" value of type 
"Microsoft.Azure.Management.Monitor.Management.Models.ActivityLogAlertActionGroup" to type "Microsoft.Azure.Management.Monitor.Management.Models.RuleAction".  "

How can I overcome this problem ? How can I associate a existing Action Group through PowerShell ?
