What could cause the INVALID_MARKET exception?

Following the example code for the Bittrex marketdata demo, the exchange responds with a disappointing HTTP message. Here’s the exception:

Exception in thread "main" si.mazi.rescu.HttpStatusIOException: Can not construct instance of org.knowm.xchange.bittrex.v1.dto.marketdata.BittrexTickerResponse, problem: null at [Source: {"success":false,"message":"INVALID_MARKET","result":null}; line: 1, column: 58]

Is this reproducible on someone else’s machine? Am I doing something wrong?

Thanks in advance!

Use the currency pairs constants.

Yep…not just the demo. Just did some debugging and found that the BittrexUtils.toPairString is causing it. public static String toPairString(CurrencyPair currencyPair) { return currencyPair.counter.getCurrencyCode().toUpperCase() + "-" + currencyPair.base.getCurrencyCode().toUpperCase(); }

I guess its because of not properly constructed CurrencyPair object param.

My Request was like this: CurrencyPair cp = new CurrencyPair("btc", "ltc"); List<BittrexUserTrade> lt = serviceRaw.getBittrexTradeHistory(cp);
