Got exception from getCandlestickBars()

[blaizechuang]

Hi, I got an exception after calling following code
client.getCandlestickBars(TradingPairSymbols.BTCPairs.ETH_BTC, CandlestickInterval.DAILY);

It seems that the type mapping in [BinanceApiServiceGenerator.java:60] is incorrect.

Stacktrace:
com.binance.api.client.exception.BinanceApiException: com.fasterxml.jackson.databind.exc.InvalidFormatException: Can not construct instance of java.lang.Long from String value ("0.08000000"): not a valid Long value at

I am facing the same issue either. Is there any solution found so far?

Hi, I'm unable to reproduce your problem, running client.getCandlestickBars("ETHBTC", CandlestickInterval.DAILY) works well for me. Can you please share your code @freezerdragon @blaizechuang ? Thanks.

Hello @joaopsilva , thanks for quick response. I am trying to use this library for an android project. And importing it from both https://jitpack.io/#binance-exchange/binance-java-api or compiled JAR library. Neither worked so far.

My code is straightforward as ;

Log.d("BINANCE", "Clicked");
        BinanceApiClientFactory clientFactory = BinanceApiClientFactory.newInstance();
        //sync
        BinanceApiRestClient client = clientFactory.newRestClient();
        List<Candlestick> candlesticks = client.getCandlestickBars("NEOETH", CandlestickInterval.WEEKLY);

When I run this, I get ->

This exact result.

@joaopsilva is there any progress?

[joaopsilva]

Hi @freezerdragon , I am really unable to reproduce this problem, I've tried on multiple JDKs and it works. The retrofit library has since been updated, could you please update your repo and try again? Thanks.

Same error here, only affected on Android
Repo:

implementation 'com.github.binance-exchange:binance-java-api:master-SNAPSHOT'

Code:

BinanceApiRestClient client = BinanceApiClientFactory.newInstance().newRestClient();
List<Candlestick> candlestickBars = client.getCandlestickBars("ZRXETH", CandlestickInterval.HOURLY, 100, null, null);
System.out.println("Candlestick size " + candlestickBars.size());
