azure-sdk-for-net: [BUG] Storage container CreateIfNotExistsAsync -> null exception in Azure.Core if container already exists

Describe the bug Getting null exception from Azure.Core if trying to create a blob container that already exists, but I am using CreateIfNotExistsAsync.

Expected behavior CreateIfNotExistsAsync succeeds

Actual behavior (include Exception or Stack Trace) CreateIfNotExistsAsync succeeds if container does NOT already exist, but throws null exception if container DOES already exist.

To Reproduce Steps to reproduce the behavior (include a code snippet, screenshot, or any additional information that might help us reproduce the issue)

  1. Create BlobServiceClient instance
  2. Create containerClient by calling client.GetBlobContainerClient, with a container name
  3. await containerClient.CreateIfNotExistsAsync(cancellationToken: cancellationToken);

If the container ALREADY EXISTS, it results in this Exception:

System.NullReferenceException HResult=0x80004003 Message=Object reference not set to an instance of an object. Source=Azure.Core StackTrace: at Azure.Response1.op_Implicit(Response1 response) at FastPathCommon.AzureStorage.BlobStorageV12.<CreateContainerIfNotExists>d__5.MoveNext() in C:\git\FastPath\src\FastPath\FastPathCommon\AzureStorage\BlobStorageV12.cs:line 38

Environment:

  • Azure.Storage.Blobs 12.2.0 with
  • .NET Core 3.1, Windows 10, Visual Studio 2019

issue #109 has existed for 8 years (!) and seems to be the exact same thing.

As mentioned by @hallgeirl all sorts of methods that should not throw are throwing exceptions.

Do I understand this correctly that you cannot provide a fix for that due to breaking changes and the recommended way to work around this is to try/catch the NullRefEx?

A quick skim here makes me think it’s happening because CreateIfNotExists returns null for ContainerAlreadyExists and then Response<T>'s implicit cast to T fails to unwrap a null response. If that’s the case, then

await container.CreateIfNotExistsAsync(...); // Make sure it already exists
BlobContainerInfo containerInfo = await container.CreateIfNotExistsAsync(...);

should fail here with a nullref when the Response<BlobContainerInfo> is implicitly unwrapped. A workaround would be replacing it with

await container.CreateIfNotExistsAsync(...); // Make sure it already exists
Response<BlobContainerInfo> response = await container.CreateIfNotExistsAsync(...);
if (response != null)
{
	BlobContainerInfo containerInfo = response.Value;
    // ...
}

@amnguye - Can you try that out? If that’s what’s wrong, we can brainstorm whether there’s something better to return here.
