unable to access the StatusCode property when the Status of operation is “Unauthorized”. It seems to be not accessible via CosmosException unlike other exception types.

We are continuously addressing and improving the SDK, if possible, make sure the problem persist in the latest SDK version.

Describe the bug
Unable to access the StatusCode property when the Status of operation is “Unauthorized”.
It seems to be not accessible via CosmosException unlike other exception types.

To Reproduce

try
{
var cosmosClient = new CosmosClient(
connectionProperties.EndpointUri,
connectionProperties.PrimaryAuthorizationKey,
new CosmosClientOptions()
{
ConnectionMode = ConnectionMode.Direct,
});
var accountProperties = cosmosClient.ReadAccountProperties( ...parameter values...) ... missed adding an operation earlier.
}
catch (CosmosException cosmosException)
{
if (cosmosException.StatusCode.Equals(HttpStatusCode.Unauthorized))
{
// This condition is never met. Instead base “Exception” is thrown
}

}
catch (Exception ex)
{
// Fails on following condition when "statusCode" is "Unauthorized"
var code = ((Microsoft.Azure.Documents.DocumentClientException)ex).StatusCode;
}

Expected behavior
CosmosException type should inlcude the Status code even for "Unauthorized" operation

Actual behavior
Base Exception is thrown without access to the "Status Code"
Environment summary
SDK Version: 3.1.1
OS Version : Windows

Is your invalid key a valid base64 value or just a random string?

[arunmannengal-zz]

It is a Valid base 64 string. Essentially I took a valid SecretKey value and replaced a character to induce this error.

[ealsur]

Which character? Because I'm using your code with the Emulator credentials, and changing one of the middle letters, and it doesn't throw, because it's a valid base64 still.

Now, if I change the last ones for example, I get a FormatException, because the string is no longer a valid base64.

Check the typeof of the Exception you get.

We seem to be throwing a DCE on Unauthorized:

try
{
    var cosmosClient = new CosmosClient(
        "https://localhost:8081",
        "C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIr/Jw==",
        new CosmosClientOptions()
        {
            ConnectionMode = ConnectionMode.Direct,
        });

    var document = await cosmosClient.GetContainer("test", "test").ReadItemAsync<dynamic>("test", new PartitionKey("test"));
}
catch (Exception ex)
{
    // This is a DCE
}
