I can not get data

Created by: ghost

Hi, BBlanchon!

I need help. Use ESP8285.

void onEvent(AsyncWebSocket * server, AsyncWebSocketClient * client, AwsEventType type, void * arg, uint8_t * data, size_t len) {
  if (type == WS_EVT_DATA) {
    Serial.println((char*)data);        // I get a valid package (as below)
    DynamicJsonDocument doc;
    DeserializationError error = deserializeJson(doc, (char*)data);
    if (error) {
      Serial.println("Error Pack");
      return;
    }
    JsonObject root = doc.as<JsonObject>();

    if (root["setSC"]) {
      Serial.println(root["setSC"]);  // I get nothing???
    }
  }
}

This is the received package from websocket:

{"setSC":
  [
    {
      "ID":0,
      "NM":"-= 0 =-",
      "EN":false,
      "AP":"10",
      "EV":[{"da":"82894F","pr":[[0,5],[0,4]]}],
      "AC":[{"da":"82894F","pr":[[3,2],[0,2]]}]
    },
    {
      "ID":1,
      "NM":"-= 1 =-",
      "EN":true,
      "AP":"12",
      "EV":[{"da":"82894F","pr":[[1,3],[0,0]]}],
      "AC":[{"da":"82894F","pr":[[2,3],[0,4]]}]
    }
  ]
}

I need to get only an array belonging to "setSC" How do I get the whole array?
