Cannot invoke "org.ton.java.tonlib.types.LastTransactionId.getLt()"

[SaitgalinKhannan]

java.lang.NullPointerException: Cannot invoke "org.ton.java.tonlib.types.LastTransactionId.getLt()" because the return value of "org.ton.java.tonlib.types.FullAccountState.getLast_transaction_id()" is null at org.ton.java.tonlib.Tonlib.getRawTransactions(Tonlib.java:510)

This code gives an error:

val tonlib: Tonlib = Tonlib.builder().build() val address: Address = Address.of("EQA870ez59EjeBmDNWBaQhvUTeGRKeJYJbJ_quKgCT__UjWr") val rawTransactions = tonlib.getRawTransactions(address.toString(false), null, null)

Is this a bug or is it supposed to be like this? This does not always happen. If you call the function a second time, everything works fine.

Hi, I cannot reproduce your issue. This code works fine:

    @Test
    public void testIssue13() {
        Tonlib tonlib = Tonlib.builder().build();
        Address address = Address.of("EQA870ez59EjeBmDNWBaQhvUTeGRKeJYJbJ_quKgCT__UjWr");
        RawTransactions txs = tonlib.getRawTransactions(address.toString(false), null, null);
        for (RawTransaction tx : txs.getTransactions()) {
            if (nonNull(tx.getIn_msg()) && (!tx.getIn_msg().getSource().getAccount_address().equals(""))) {
                log.info("{}, {} <<<<< {} : {} ", Utils.toUTC(tx.getUtime()), tx.getIn_msg().getSource().getAccount_address(), tx.getIn_msg().getDestination().getAccount_address(), Utils.formatNanoValue(tx.getIn_msg().getValue()));
            }
            if (nonNull(tx.getOut_msgs())) {
                for (RawMessage msg : tx.getOut_msgs()) {
                    log.info("{}, {} >>>>> {} : {} ", Utils.toUTC(tx.getUtime()), msg.getSource().getAccount_address(), msg.getDestination().getAccount_address(), Utils.formatNanoValue(msg.getValue()));
                }
            }
        }
    }

output:

which version of ton4j are you using? I have tested with the latest one.

latest tonlibjson and 0.4.3 ton4j

During synchronization, an error occurs, the message "Synchronized: 90.91%" appears and after a few seconds the error "java.lang.NullPointerException" is displayed. But this happens rarely (this happens one time out of ten) and only if the request is made immediately after the program is turned on.

Synchronized: 90.91% java.lang.NullPointerException: Cannot invoke "org.ton.java.tonlib.types.LastTransactionId.getLt()" because the return value of "org.ton.java.tonlib.types.FullAccountState.getLast_transaction_id()" is null at org.ton.java.tonlib.Tonlib.getRawTransactions(Tonlib.java:510) at com.khannan.ton.Ton$tonlibTransactions$2.invokeSuspend(Ton.kt:35) at com.khannan.ton.Ton$tonlibTransactions$2.invoke(Ton.kt) at com.khannan.ton.Ton$tonlibTransactions$2.invoke(Ton.kt)

Yes, this happens to me as well. The reason for that is that Lite Server cannot response in time, one needs just to handle this case.
