Sprint:nxFG 11.1.3
The KeyValueBlobTransientStore should be robust when getting or garbage collecting a blob that's missing from the underlying blob provider.
This situation may happen if the KeyValueBlobTransientStore has an underlying blob provider that can be accessed by another service and whose blobs can be removed without the knowledge of the KeyValueBlobTransientStore.

The above stack trace also shows a consequence: if there's an error while getting the blob during GC, then the GC is not stopped correctly.
