BigNumber undefined help

[billtlee]

Hi,

So, I have the following:

console.log(nft.auctionDetails.bidCount);
console.log(ethers.utils.BigNumber.isBigNumber(nft.auctionDetails.bidCount));

The first console.log produced:
{ type: 'BigNumber', hex: '0x00' }

But the second one is giving me:

TypeError: Cannot read property 'isBigNumber' of undefined

Does anyone know what I might be doing wrong?

I tried ethers.utils.BigNumber.from, ethers.utils.BigNumber.toString(), all getting undefined.

Here is the console.log of the whole nft object:
{
price: '0.1',
tokenId: { type: 'BigNumber', hex: '0x02' },
itemId: 1,
saleCount: 0,
seller: '0x61A3d01D4F7Ab602E44F24E7D139395c67069a05',

highestBid: '0.1',
bidCount: { type: 'BigNumber', hex: '0x00' }
}
}

Thanks in advance!

In v5, BigNumber moved out of utils, so you just have to remove .utils and directly use ethers.BigNumber.

what about v6 bro, i tried ethers.BigNumber.from(1.2)
but failed with TypeError: Cannot read properties of undefined (reading 'from')

In v6 there is no BigNumber class, it uses javascript's native BigInt class. You can look at the docs here
