Unable to send BEP20 token

[ExchangeAssets]

I want to send BEP20 token but I get an error, here is my code:

function web3_send_token($from, $to, $amount, $contract_address, $private) {
    $web3 = new Web3('https://bsc-dataseed1.binance.org:443');
	
	$web3->eth->gasPrice(function ($error, $gasPrice) use (&$result) {
        if($error) {
            $result = [
                'error' => 'Ошибка получения gasPrice: ' . $error->getMessage()
            ];
            return;
        }
        $result['gasPrice'] = $gasPrice;
    });
	
	$web3->eth->getTransactionCount($from, 'pending', function ($error, $nonce) use (&$result) {
        if($error) {
            $result = [
                'error' => 'Ошибка получения nonce: ' . $error->getMessage()
            ];
            return;
        }
        $result['nonce'] = $nonce;
    });
	$abi = '[{"constant":false,"inputs":[{"name":"_to","type":"address"},{"name":"_value","type":"uint256"}],"name":"transfer","outputs":[],"payable":false,"stateMutability":"nonpayable","type":"function"}]';	
    
	$contract = new Contract($web3->provider, $abi);
	$amount = bcmul($amount, bcpow('10', 18), 0);
	
	$contract->at($contract_address)->estimateGas('transfer', $to, $amount, ['from' => $from], function ($error, $gas) use (&$result) {
		if($error) {
			$result = [
				'error' => 'Ошибка оценки газа: ' . $error->getMessage()
			];
			return;
		}
		$result['gas'] = $gas;
	});
	
	$data = $contract->at($contract_address)->getData('transfer', $to, $amount);		

	$transaction = new Transaction([
		'to' => $contract_address,
		'value' => '0x0',
		'gasPrice' => '0x' . dec_hex($result['gasPrice']->toString()),
		'gas' => '0x' . dec_hex($result['gas']->toString()),
		'nonce' => '0x' . dec_hex($result['nonce']->toString()),
		'data' => $data,
		'chainId' => 56
	]);

	$signedTransaction = '0x' . $transaction->sign($private);

	$web3->eth->sendRawTransaction($signedTransaction, function ($error, $txid) use (&$result) {
		if($error) {
			$result = [
				'error' => 'Ошибка отправки транзакции: ' . $error->getMessage()
			];
			return;
		}

		$result = [
			'txid' => $txid
		];
	});
	
    return $result;
}
