Docker remote repository get a wrong schema when the Metadata cache retrieval period is set to 0

Remote docker repository pointing to another artifactory instance and the metadata cache retrieval period set to 0 fetched the wrong manifest version.

 

For example: Docker pull busybox:2.0.0 image from Artifactory A proxying to Artifactory B's local has the following logs:

But however the manifest.json file of the busybox:2.0.0 is below:

{ "schemaVersion": 2, "mediaType": "application/vnd.docker.distribution.manifest.v2+json", }

 

And the error from the docker client is this:

docker pull {Art Url}:8082/docker-test/busybox:2.0.0
