I am trying to disable an alert rule via powershell, but I am getting the following error:

Get-AzMetricAlertRuleV2 -ResourceGroupName "myresourcegroupname"  -Name "alertname" | Add-AzMetricAlertRuleV2 -DisableRule

Add-AzMetricAlertRuleV2: Cannot validate argument on parameter 'TargetResourceRegion'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

I have tried it without the | Add-AzMetricAlertRuleV2 -DisableRule:

Get-AzMetricAlertRuleV2 -ResourceGroupName "myresourcegroupname"  -Name "alertname"
Output:

My previous command was telling me that 'TargetResourceRegion' is null or empty. And that's right corresponding to the output above. But how can I disable that alert rule from powershell, with an empty TargetResourceRegion?
