Error in java api while fetching candle data

[HariCharan]

candleData method in SmartConnect class of java is throwing error because of the below issue

Present code (throwing error):

public String candleData(JSONObject params) {
		try {
			String url = routes.get("api.candle.data");
			JSONObject response = smartAPIRequestHandler.postRequest(this.apiKey, url, params, accessToken);
			System.out.println(response);
			return response.getString("data");
		} catch (Exception | SmartAPIException e) {
			System.out.println(e.getMessage());
			return null;
		}
	}

corrected code:

public JSONArray candleData(JSONObject params) {
		try {
			String url = routes.get("api.candle.data");
			JSONObject response = smartAPIRequestHandler.postRequest(this.apiKey, url, params, accessToken);
			System.out.println(response);
			return response.getJSONArray("data");
		} catch (Exception | SmartAPIException e) {
			System.out.println(e.getMessage());
			return null;
		}
	}
