Azure function will not create blob metadata

I like to write some metadata to an existing blob. The function runs without any error but the blob metadata not changes or not created. 

 #r "Microsoft.WindowsAzure.Storage"

 using System; using System.Configuration; using System.Net; using
 System.Text; using Microsoft.Azure; using
 Microsoft.WindowsAzure.Storage; using
 Microsoft.WindowsAzure.Storage.Blob;

 public static void Run(string myQueueItem, ILogger log) {
     string[] myQueueItems = myQueueItem.Split(':');

     string DocumentID = myQueueItems[0];
     string MetaDataKey = myQueueItems[1];
     string MetaDataValue = myQueueItems[2];


     CloudStorageAccount storageAccount = CloudStorageAccount.Parse("");
     CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
     CloudBlobContainer container = blobClient.GetContainerReference("test123");

     CloudBlob blob = container.GetBlobReference("teams.xlsx");
     blob.FetchAttributesAsync();

     if (blob.Metadata.ContainsKey(MetaDataKey))
     {
         blob.Metadata[MetaDataKey] = MetaDataValue;
     }
     else{
         blob.Metadata.Add(MetaDataKey, MetaDataValue);
     }

     blob.SetMetadataAsync();

     log.LogInformation($"C# Queue trigger function processed: {blob.Name}");

 }

Input: Test:Test:Test Output: C# Queue trigger function processed:teams.xlsx

The functions runs but not create the metadata “Test” with the value “Test” on the blob teams.xlsx.
