Registry-cli issues with nexus

[prudhvigodithi]

Hey I have been using docker registry provided by nexus, to clean up images using this registry-cli, works for listing the images with tags with layers but coming to delete the image with layers or using --delete-all flag, gives me an error like "Try adding flag --digest-method=GET" "tag digest not found: 404." Though i have added the tag --digest-method GET, below I shall attach the command what I am trying to use

docker run --rm anoxis/registry-cli -l : -r http://myregistry:port --digest-method=GET --delete-all --tags-like "customtag" ---->trying to delete all images with all layers that has customtag as tag

when I try to run this i get "Try adding flag --digest-method=GET tag digest not found: 404. ", this error gets only for few tags, whereas I see some tags got deleted and other tags I get this error, not sure why, secondly the deleted tags I cannot view them from nexus UI nor I am not able to pull them which is good and which i what I want, but though few tags where deleted also with layers the storage for nexus does not seems to get reduced, even after I ran compact blob store and docker purge images tasks from nexus UI after running the above command, so I am at a point using this registry-cli which deletes few tags but does not reclaim any space and gets 404 error for other tags, also tried adding other options like ---delete-all, --digest-method DELETE, but gets the same error, any idea, suggestion or fix for this, using nexus Version 3.3.0-01.

output:
docker run --rm anoxis/registry-cli -l user:Pass -r https://myregistey:port --delete-all --tags-like "customtag" --no-validate-ssl --digest-method GET

Try adding flag --digest-method=GET
deleting tag customtag
tag digest not found: 404.
