bitcore-lib-cash: Error upon attempt to spend from a 2-of-8 multisig P2SH address

[ghost]

I may not spend coins from a 2-of-8 multisig. When I'm trying to do it I get an error "TypeError: "value" argument is out of bounds".

For example:

const privateKeys = [
	new bch.PrivateKey.fromRandom(),
	new bch.PrivateKey.fromRandom(),
	new bch.PrivateKey.fromRandom(),
	new bch.PrivateKey.fromRandom(),
	new bch.PrivateKey.fromRandom(),
	new bch.PrivateKey.fromRandom(),
	new bch.PrivateKey.fromRandom(),
	new bch.PrivateKey.fromRandom(),
];
const publicKeys = privateKeys.map(bch.PublicKey);
const address = new bch.Address(publicKeys, 2); // 2 of 8
const utxo = {
	'txId' : '153068cdd81b73ec9d8dcce27f2c77ddda12dee3db424bff5cafdbe9f01c1756',
	'outputIndex' : 0,
	'address' : address.toString(),
	'script' : new bch.Script(address).toHex(),
	'satoshis' : 20000
};
const transaction = new bch.Transaction()
	.from(utxo, publicKeys, 2)
	.to('mtoKs9V381UAhUia3d7Vb9GNak8Qvmcsme', 20000)
	.sign([privateKeys[0]]);

console.log(transaction.toString())

The result is an error
