Partial Clone does not work

I’m trying to use the new partial clone feature. I’ve followed this but it doesn’t seem to be working.

I’m using git clone --filter=blob:limit=1m https://repo.git on the client but I’m getting warning: filtering not recognized by server, ignoring and the entire repo is being cloned. Happens with GitLab 13.0.6 and git v2.27 on the server and the client. Do you have to do something else to enable this feature on the server?
