How to decode bytes parameter of onERC721Received

I'm using safeTransferFrom to transfer a token. I'm using the fourth parameter bytes to pass a value and decode it from onERC721Received. The problem is that the decode value is different from what is passed.

:1234: Code to reproduce

How I'm passing the value:

const sendingContract = artifacts.require("SendingContract");
const admin = accounts[4];
const tokenOwner = accounts[0]
const tokenRecipient = accounts[1]
const contract = await sendingContract.deployed({ from: admin });
// Uses an existing tokenId 

try {
    const price = web3.utils.toWei("1", "ether");
    const priceConverted = web3.eth.abi.encodeParameter('bytes', price);  
    await contract.methods['safeTransferFrom(address,address,uint256,bytes)'](tokenOwner, tokenRecipient, tokenId, priceConverted, { from: tokenOwner })
} catch (error) {

How I'm receiving the value:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

contract ReceivingContract is IERC721Receiver {
    uint price;

    function onERC721Received(address, address, uint256 _tokenId, bytes calldata _data) public virtual override returns (bytes4) {
        (uint _price) = abi.decode(_data, (uint));   
        price = _price;
        return this.onERC721Received.selector;

Check the received value:

const price = await;
console.log(price); // BN { negative: 0, words: [ 32, <1 empty item> ], length: 1, red: null }
console.log(price.toString()) // 32

I'm not sure how the stringified received value is 32 and how to receive the value in a Wei form.
