"Unhandled rejection RpcError: Wallet file not specified" when attempting to get wallet balance

Hi,

I am attempting to execute the following script:

const Client = require('bitcoin-core');
const client = new Client({
  username: 'myuser',
  password: 'mypassword',
  //wallet: 'wallet.dat',  //also tried this
  wallet: 'MyWallet',
  version: '0.17.0'
});

client.getBalance().then((help) => console.log(help));

Expected behavior is to get the balance of MyWallet. Actual behavior is the following error:

Unhandled rejection RpcError: Wallet file not specified (must request wallet RPC through /wallet/<filename> uri-path).

This is with bitcoin-core@2.0.0 and bitcoind 0.17.0.

Here is the output from bitcoin-cli and bitcoind, which shows the wallet works well with bitcoin-cli:

My wallet file is /vol0/bitcoin/wallet.dat

I would appreciate any insight you could share on this. Thank you.
