I get this error: error: cannot check existence of resource '/providers/Microsoft.Management/managementGroups/ChildGroup/subscriptions/sa': status code 400, {"Message":"The request is invalid."}
With the code Pulumi.AzureNative.Management.ManagementGroupSubscription s =
new Pulumi.AzureNative.Management.ManagementGroupSubscription("sa", new Pulumi.AzureNative.Management.ManagementGroupSubscriptionArgs
{
GroupId = "ChildGroup",
SubscriptionId = "sa"
});;
