DataSyncLog Runbook without specify SyncGroup

In sql-server-samples/samples/features/sql-data-sync/DataSyncLogPowerShellRunbook.ps1 when I don't specify a SyncGroup and it tries to run the following line in testing environment.

$SyncGroupName = Get-AzureRmSqlSyncGroup -ResourceGroupName $ResourceGroup -ServerName $Server -DatabaseName $Database | select -ExpandProperty SyncGroupName

I run into the below exception. I'm not a PS expert, but this is defined I believe. https://docs.microsoft.com/en-us/powershell/module/azurerm.sql/get-azurermsqlsyncgroup?view=azurermps-4.4.0

Get-AzureRmSqlSyncGroup : The term 'Get-AzureRmSqlSyncGroup' is not recognized as the name of a cmdlet, function,

Inizia da sql-server-samples/samples/features/sql-data-sync/DataSyncLogPowerShellRunbook.ps1 intorno alla riga 165, quindi esamina la documentazione collegata di Get-AzureRmSqlSyncGroup. Esegui il runbook nello scenario di test segnalato senza specificare una SyncGroup e analizza l'eccezione relativa al comando mancante. Il lavoro è completato quando quello scenario non fallisce più durante la ricerca della SyncGroup.
