As you did not specify a docker extract destination, the default is being used. As of shrink/[email protected] the default does not include a dot prefix. v3.0.0: ".extracted-1731437791890", v3.0.1: "extracted-1731437791890" See https://github.com/shrink/actions-docker-extract/issues/28 for context. No action is required unless this Workflow depends upon the dot prefix.
