Yeah, v3 uses a newer package, it seems it did not version negotiate

will need to investigate

[RA341]

v3 has switched to a newer package and is using newer APIs

you will need to upgrade your docker install to use v3

upgrade to engine v25 or newer https://docs.docker.com/engine/release-notes/25.0/

Unfortunately this change affects Synology users that can't install Dockman anymore since Synology did not update their docker engine.
