Image manifest error when mirroring images for a disconnected installation

Issue

• The error happens when the following command (or similar) is executed:

# oc adm -a ${LOCAL_SECRET_JSON} release mirror --from=quay.io/${PRODUCT_REPO}/${RELEASE_NAME}:${OCP_RELEASE} --to=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY} --to-release-image=${LOCAL_REGISTRY}/${LOCAL_REPOSITORY}:${OCP_RELEASE} --apply-release-image-signature

• Many images are usually pushed without any problem, but the process becomes interrupted at some point. Example of errors returned:
