Default message: unsupported docker push operation; only blob upload and manifest push are implemented
HTTP status:400(client)
Problem. Docker push request matched neither blob upload, manifest
push, nor blob HEAD. Cause. The repository received an OCI
request type it does not implement (e.g. cross-repo mount blob link
without upload). Fix. Use the standard OCI Distribution v2 push
flow; contact support if you need the requested operation. HTTP 400.
