get transaction amount values using Besu and webj in java

Question

Im trying to get transaction amount of Besu transaction using web3j and java. Unfortunately without success. Input allways return 0x. Can anyone tell me what to change?

        String transactionHash = "0xe7df62446f91106dea2cca0d9cdb2655cd15738d6cdad00f5bb5327fd35648dd";
        Web3j web3j = Web3j.build(new HttpService(Vars.nodeUrl));
        EthGetTransactionReceipt transactionReceipt = web3j.ethGetTransactionReceipt(transactionHash).send();
        System.out.println("Transaction receipt: " + transactionReceipt.getTransactionReceipt().get());

        List<Log> logs = transactionReceipt.getTransactionReceipt().get().getLogs();

        System.out.println("Log size: "+logs.size());

        String inputdata;
        Optional<Transaction> tx = web3j.ethGetTransactionByHash(transactionHash).send().getTransaction();
        if (tx.isPresent()) {
            inputdata = tx.get().getInput();
            System.out.println("Input data: "+inputdata);
        }

        Optional<TransactionReceipt> transReceipt = web3j.ethGetTransactionReceipt(transactionHash).send().getTransactionReceipt();
