Error when calling smart contract from js

It's probably a noob problem but I can't call a smart contract with this code (replace the secret key by any of yours):

const { WalletClient, ClientFactory, Args, fromMAS, toMAS, DefaultProviderUrls, CHAIN_ID } = require('@massalabs/massa-web3');

const SC_ADDRESS = 'AS12qzyNBDnwqq2vYwvUMHzrtMkVp6nQGJJ3TETVKF5HCd4yymzJP';

async function test() {

    const baseAccount = await WalletClient.getAccountFromSecretKey('XXX');
    const web3Client = await ClientFactory.createDefaultClient(DefaultProviderUrls.BUILDNET, CHAIN_ID.BuildNet, true, baseAccount);

    const res = await web3Client.smartContracts().callSmartContract({
        maxGas: BigInt(200000), 
        coins: BigInt(1), 
        targetAddress: SC_ADDRESS, 
        functionName: "test", 
        parameter: new Args(),
        fee: fromMAS(0.01)
      })
}

test();

I get this error:

node:buffer:319
  throw new ERR_INVALID_ARG_TYPE(
        ^

TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be of type string or an instance of Buffer, ArrayBuffer, or Array or an Array-like Object. Received undefined

I have node 22 and massa-web3 4.0.1, and I call the code in a js file with node file.js. The sc address and functionName are examples, I get the same error whatever these values.

Do you have any idea ? Thank you!
