Cannot return best route for TradeType.EXACT_OUTPUT

[lokesh-systango]

The SDK returns the error

Cannot return best route

for using TradeType as EXACT_OUTPUT

Steps to reproduce -

`

import { Fetcher, Route, Token, TokenAmount, Trade, TradeType } from "quickswap-sdk";

const provider = new ethers.providers.JsonRpcProvider(httpsUrl, chainId);

// Create contract instances for input and output tokens
const contractIn = new ethers.Contract(token, erc20Abi, provider);
const contractOut = new ethers.Contract(StableCoinAddress, erc20Abi, provider);

// Helper function to get token details
const getToken = async function (contract: ethers.Contract): Promise<Token[]> {
  const [dec, symbol, name] = await Promise.all([contract.decimals(), contract.symbol(), contract.name()]);
  return [new Token(chainId, contract.address, dec, symbol, name)];
};

// Retrieve token details for input and output tokens
const [tokenIn] = await getToken(contractIn);
const [tokenOut] = await getToken(contractOut);

// Fetch pair data and create route
const pair = await Fetcher.fetchPairData(tokenOut, tokenIn, provider);
const route = new Route([pair], tokenOut);

// Map route addresses and create trade instance
const routePathAddresses = route.path.map((token) => token.address);

const amountIn = new TokenAmount(tokenOut, ethers.utils.parseUnits(amount, tokenOut.decimals).toString());
const trade = new Trade(route, amountIn, TradeType.EXACT_OUTPUT);

`

This code runs fine for the case of EXACT_INPUT but gives this error for EXACT_OUTPUT.
