What happened in your environment?
Suppose I have below artifact which refers a zero-length blob:
$ oras manifest fetch --pretty localhost:5000/test:config
{
"schemaVersion": 2,
"mediaType": "application/vnd.oci.image.manifest.v1+json",
"artifactType": "my.test/example",
"config": {
"mediaType": "bar/test",
"digest": "sha256:e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855",
"size": 0
},
"layers": [
{
"mediaType": "application/vnd.oci.image.layer.v1.tar",
"digest": "sha256:86c1503eb091280c98d8519c344f41ffcb03545662f0122c76d8f0e6b84e4a33",
"size": 7,
"annotations": {
"org.opencontainers.image.title": "foo"
}
}
],
"annotations": {
"org.opencontainers.image.created": "2023-11-03T01:47:25Z"
}
}Copying the artifact will show
