getPair call via Ethers.Contract does not return a pair address

Hello,

When I call following getPair under uniswapFactory contract I created via ethers.Contract it doesn´t return any pair address.

const UniswapV2Factory = require("./build/contracts/IUniswapV2Factory.json");

uniswapFactory = new ethers.Contract(
		'0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f', // uniswap v2 factory address in Etherscan mainnet
		UniswapV2Factory.abi, wallet
	);

	const pairAddress = await uniswapFactory.getPair(wethAddress, otherAddress);
  	const pair = new Contract(pairAddress, UniswapV2Pair.abi, wallet);
	console.log("yeah2!");

Strange thing is if I removed await keywork it returns Promise { }.

However, if I run await uniswapFactory.getPair(wethAddress, otherAddress); directly under Truffle console it resolves the pair address correctly.

Any suggestions would be greatly appreciated as it´s been bugging me also for a very long time.

Thank you

What error do you see?
