How to parse complex nested json using chronical-wired in tree-like manner?

Question

I have a valid json:

{
    "arg": {
        "channel": "a",
        "sub": "b"
    },
    "action": "update",
    "data": [{
        "a": [
            [
                "0.35543",
                "199.194504",
                "0",
                "2"
            ],
            [
                "0.3556",
                "0",
                "0",
                "0"
            ]
        ],
        "b": [],
        "ts": "122"
    }]
}

And i want to parse it using chronicle-wired, but getting erorrs.

Let's get a attribute:

ValueIn data1 = wire.read("data");
while (data1.hasNextSequenceItem()) {
  data1.sequence(out, this::read0);
}
        
private void read0(Object out, ValueIn valueIn) {
  valueIn.applyToMarshallable((f) -> {
  ValueIn a = f.read("a");
  ValueIn b = f.read("b");
  return out;
});
}

Throws net.openhft.chronicle.core.io.IORuntimeException: Unsupported type [
