bitcoin-php: Error: Missing inputs

Hello.

I have installed bitcoin core in regtest mode and i’m connecting via RPC Client. I’m trying to push the signed transaction but i get “Missing inputs” error.

My code:

$addressCreator = new AddressCreator();
$transactionBuilder = TransactionFactory::build();
$privKeyFactory = new PrivateKeyFactory();

$bitcoin = new BaseBitcoin();
$bitcoin->setNetwork(NetworkFactory::bitcoinRegtest()); // Regtest

$privateKey = $privKeyFactory->fromWif($sourceAddressKey, $bitcoin->getNetwork());
$txOuts = [];

// Adding inputs
foreach ($txInputs as $txInput) {
	$transactionBuilder->input($txInput['hash'], $txInput['idx']);

	array_push($txOuts, new TransactionOutput(
		$txInput['value'],
		ScriptFactory::fromHex($txInput['script'])
	));
}

// Adding destination address
$transactionBuilder->payToAddress(
	$spendAmount,
	$addressCreator->fromString($destAddreess)
);

// Adding own address for receive change
$transactionBuilder->payToAddress(
	$changeAmount,
	$addressCreator->fromString($sourceAddress)
);

$transaction = $transactionBuilder->get();

$signer = new Signer($transaction);
$signed = null;

// Signing
foreach ($txOuts as $key => $txOut) {
	$signer->sign($key, $privateKey, $txOut);
}

$signed = $signer->get();

return $signed->getHex();

Result example:

• Balance: 200000000 (Satoshi)
• Spend amount: 100000000 (Satoshi)
• Fee amount: 3616 (Satoshi)
• change amount: 99996384 (Satoshi)

Also you can see In this particular example that the fee is 3616 but as you can see in “fees: 0” in transaction.

So, what’s the problem, my code or bitcoin core?
