`Error: destinationAmountSwapped is zero` Raydium CurveCalculator

I am trying to get the swap results before making a swap using from Raydium V2 SDK

  const swapResult = CurveCalculator.swap(    inputAmount,    baseIn ? baseReserve : quoteReserve,    baseIn ? quoteReserve : baseReserve,    new BN(feeConfigs[0].tradeFeeRate)  );

But it keeps failing with

Error: destinationAmountSwapped is zero
