ERROR POST https://mainnet.infura.io/v3/ 401 when using BSC

[piatpawel]

hello,
I have the same problem to configure BSC network as described on github using vanilla JavaScript:
https://github.com/Web3Modal/web3modal/issues/295

My js code:

const providerOptions = {
  walletconnect: {
    package: WalletConnectProvider,
    options: {
      rpc: {
        56: 'https://bsc-dataseed1.binance.org/'
      },
      chainId: 56
    }
  }
}

  web3Modal = new Web3Modal({
    cacheProvider: false, // optional
    providerOptions, // required
    disableInjectedProvider: false, // optional. For MetaMask / Brave / Opera.
  });

ERROR
