"TypeError: Cannot read property ‘hexString’ of undefined’

Hi,

Ive been trying to customize this arbitrage bot for Uniswap Sushiswap but I keep getting this :
"TypeError: Cannot read property ‘hexString’ of undefined’

I ve been stuck on how to solve this issue for weeks now.Heres the screenshot of the code below .Thanks.

function isHexable(value) {
return (value.toHexString);
}
function addSlice(array) {
if (array.slice) {
return array;
}
array.slice = function () {
var args = Array.prototype.slice.call(arguments);
return addSlice(new Uint8Array(Array.prototype.slice.apply(array, args)));
};
return array;
}

It pretty much means that the value is undefined, because of some bug. Can you console log all the inputs you are passing to ethers js?
