Missing property "monetaryMass" in blocks received by websocket

For example, if I connect to : wss://g1.duniter.org/ws/block, here is what I receive using chromium Smart Websocket Client :

That's why Sakia considers these values invalid. The behaviour changed between 1.3 and 1.4. What do you think is the correct behaviour ?

The URL http://g1.duniter.org/blockchain/block/45614 stills contains the monetaryMass field.
