We are authing with managed identity. And it seems that we only see the exception after upgraded to version 12.8.0. Not seeing any issue in previous 12.5.0.

Expected behavior

Not throwing exception.

Actual behavior

Create new table if not exists, not throwing exceptions.

Reproduction Steps

install package <PackageReference Include="Azure.Data.Tables" Version="12.8.0" />

code snippets:

var storageName = "yourStorage";
var tableName = "yourTable";
var clientOptions = new TableClientOptions();
var credential = new DefaultAzureCredential();
string tableUrl = $"https://{storageName}.table.core.windows.net/{tableName}";

var tableClient = new TableClient(new Uri(tableUrl), tableName , credential, clientOptions);
await tableClient.CreateIfNotExistsAsync(default);

try run multiple times.

Environment

Windows Server 2019-Datacenter on Azure, running with .NET 6.
