ListBlobs does not list UnCommitted blobs

Question

I tried use blobstate to list uncommitted blobs. But GetBlobsByHierarchyAsync with BlobStates.Uncommitted return same result as with BlobStates.None.

My code

Console.WriteLine("BlobStates " + blobStates);

        await foreach (BlobHierarchyItem blobHierarchyItem in blobContainerClient.GetBlobsByHierarchyAsync(
            BlobTraits.None, blobStates))
        {
            Console.WriteLine("Blob.Name " + blobHierarchyItem.Blob.Name);
            Console.WriteLine("Blob.Properties.LastModified " + blobHierarchyItem.Blob.Properties.LastModified);
        }

Result

BlobStates Uncommitted

Blob.Name testing_6.bin Blob.Properties.LastModified 25.03.2022 6:30:04 +00:00

Blob.Name testing_7.bin Blob.Properties.LastModified 25.03.2022 6:30:25 +00:00

Blob.Name testing_8.bin Blob.Properties.LastModified 25.03.2022 13:47:46 +00:00

BlobStates None

Blob.Name testing_6.bin Blob.Properties.LastModified 25.03.2022 6:30:04 +00:00

Blob.Name testing_7.bin Blob.Properties.LastModified 25.03.2022 6:30:25 +00:00

Blob.Name testing_8.bin Blob.Properties.LastModified 25.03.2022 13:47:46 +00:00

Do I something wrong? Thanks

You can list blobs in a flat listing structure, or hierarchically

Hierarchical listing returns blobs as though they were organized into folders

To list blob versions or snapshots, specify the BlobStates parameter with the Version or Snapshot field. Versions and snapshots are listed from oldest to newest
