如何使用 web3.js 将数字作为 uint256 传递给 Solidity 函数

Question

I have a contract in Solidity :

function mint(uint256 quantity_) public payable {
        require(isPublicMintEnabled, 'minting not enabled');
        require(msg.value == quantity_ * mintPrice, 'wrong mint value');
        require(totalSupply + quantity_ <= maxSupply, 'sold out');
        require(walletMints[msg.sender] + quantity_ <= maxPerWallet, 'exceed max wallet');

        
        for (uint256 i = 0; i < quantity_; i++) {
        uint256 newTokenId = totalSupply + 1;
        totalSupply++;
        _safeMint(msg.sender, newTokenId);
        }
    }

I am trying to use the mint function using Web3.js like so:

  contract.methods.mint(amount).send({ from: state.connectedWallet })

The problem is that if I pass the amount as a JavaScript Number/String the contract fails. I tried using BigNumber from web3.utils and web3.eth.abi.encodeParameter('uint256',amount) .

The contract is deployed on Harmony ONE pops testnet.

The issue has been resolved. I had to call the contract like so:

    const value = 1 * 1e18 // 1ONE
    const amount = 1
    contract.methods.mint(amount).send({ from: state.connectedWallet, value })
