Level2 Subscription doesnt work correctly

[ghost]

Going from the documentation the following should return a Level2 Event
apex.Level2.subscribe(console.log);

Instead you get this garbled mess

ActionType:(10) [15, 1, 1623181164534, 0, 43916.83, 1, 37467.84, 2, 0.0047, 0]
LastTradePrice:undefined
NumberOfAccounts:(10) [13, 1, 1623181164534, 0, 43916.83, 1, 38340.63, 2, 0.6923, 1]
NumberOfOrders:undefined
Price:undefined
ProductPairCode:undefined
Quantity:undefined
Side:undefined
UpdateDateTime:(10) [14, 0, 1623181160956, 2, 43916.83, 0, 37437.09, 2, 0, 0]
UpdateId:(10) [12, 0, 1623181159643, 2, 43916.83, 0, 38305.21, 2, 0, 1]

apex.Trade.subscribe(console.log);

Doesn't work either, related to this.

The error comes from the fact that the subscriptions both return arrays of arrays and you guys pass it into their respective constructors Level2 and Trade which decodes them only as a single array.

Change this

new Trade(JSON.parse(o)));

To this

JSON.parse(o).map((t) => new Trade(t));

Understandable mistake to make when Level2UpdateEvent and TradeDataUpdateEvent imply singularity.
