Replace an item in Cosmos

using(ResponseMessage response = await this.container.ReplaceItemStreamAsync(stream, "itemId", new PartitionKey("itemPartitionKey"))
{
    if (!response.IsSuccessStatusCode)
    {
        //Handle and log exception
        return;
    }

    //Read or do other operations with the stream
    using (StreamReader streamReader = new StreamReader(response.Content))
