AzCosmosDBSqlContainer : “Object reference not set to an instance of an object.”

Question

I am using AzCosmosDBSqlContainer to check details of a CosmosDB (SQL api) container in PowerShell; I am getting this error

Object reference not set to an instance of an object

However Get-AzCosmosDBAccount and Get-AzCosmosDBSqlDatabase commands are working fine.

Can someone help me with this?

Command used:

$ResourceGroup="MyResourceGroup"
$CDBAccountName="mycosmosaccount"
$dbname="myDatabase"
$containername="MyContainer"

$cosmosaccount=Get-AzCosmosDBAccount -ResourceGroupName $ResourceGroup -Name $CDBAccountName 

$cosmosdbname=Get-AzCosmosDBSqlDatabase -AccountName $cosmosaccount.Name -ResourceGroupName $ResourceGroup  -Name $dbname

Get-AzCosmosDBSqlContainer -ResourceGroupName $ResourceGroup -AccountName $cosmosaccount.Name -DatabaseName $cosmosdbname.Name -Name $containername

I found a workaround after getting an update from Microsoft team.

https://github.com/Azure/azure-powershell/issues/11381

This issue is going to be fixed in upcoming version of Az.CosmosDB 0.1.4

Workaround:

 Replace "my***Name" with your own values $resourceGroupName = "myResourceGroupName" $accountName = "myAccountName" $databaseName = "mYDatabaseName" $containerName = "myContainerName" $apiVersion = "2020-03-01" $databaseResourceName = $accountName + "/" + $databaseName $containerResourceName = $databaseResourceName + "/" + $containerName $containerResourceType = "Microsoft.DocumentDB/databaseAccounts/sqlDatabases/containers" Write-Host "List containers in the database" Get-AzResource -ResourceType $containerResourceType -ApiVersion $apiVersion -ResourceGroupName $resourceGroupName -Name $databaseResourceName Write-Host "Show specified container" Get-AzResource -ResourceType $containerResourceType -ApiVersion $apiVersion -ResourceGroupName $resourceGroupName -Name $containerResourceName
