Finding the Largest Blobs Within a "Docker" Blob Store

How can I get image.name from a docker repository using this script: https://support.sonatype.com/hc/en-us/articles/115009519847-Investigating-Blob-Store-and-Repository-Size-and-Space-Usage#ExecutescriptfromTask

For maven repos, asset.name gives the artifactId, but for docker repos the code just yields the following for asset.name:

And, when I try to search/browse for one of these sha’s, I cannot find anything. Also, is there a data model reference somewhere to refer to? Thanks.
