nftables 1.0.6: snat with maps

["Mucha Marcin, Sieciuch.com" <m.mucha@xxxxxxxxxxxx>]

Hello,
I'm having trouble with moving from this snat rule:

chain source-nat {
       type nat hook postrouting priority 100; policy accept;
       ct state invalid drop;
       ip saddr 10.0.0.0/24 oif enp7s0 snat to 192.168.10.8 persistent;
       ip saddr 10.1.0.0/24 oif enp7s0 snat to 192.168.10.9 persistent;
       }
to the one that uses maps based on 
https://wiki.nftables.org/wiki-nftables/index.php/Multiple_NATs_using_nftables_maps 
:

chain source-nat {
        type nat hook postrouting priority 100; policy accept;
        ct state invalid drop;
        oif enp7s0 ip saddr maps {10.0.0.0/24 : 192.168.10.8, 
10.1.0.0/24 : 192.168.10.9};
}

My problem is - I'm getting syntax error after checking config with "nft 
-cf /etc/nftables.conf":
"/etc/nftables.conf:43:83-83: Error: syntax error, unexpected newline
    oif enp7s0 ip saddr maps {10.0.0.0/24 : 192.168.10.8, 10.1.0.0/24 : 
192.168.10.9};
                                                                         
            ^"
Could I ask you for a help?
