we are working on crowdfunding application ([GitHub - algorand/app-service](https://github.com/algorand/app-service))… while claiming the fund from an escrow account using logicsignature… we are getting null response.

You may want to try upgrading the sdk versions. This was done in a hackathon a year ago, so some of the packages used may not be compatible anymore

I upgraded SDK version but still getting the same null response  
This is my code:  
LogicsigSignature lsig = new LogicsigSignature(fund.getEscrow().getTealProgram().getBytes(), null);  
TransactionParametersResponse params = algodClient.TransactionParams().execute(headers,values).body();  
PaymentTransactionBuilder claimTransactionBuilder = Transaction.PaymentTransactionBuilder()  
.receiver(fund.getReceiverAddress())  
.closeRemainderTo(fund.getReceiverAddress())  
.sender(lsig.toAddress())  
.amount(0);  
Transaction paymentTransaction = claimTransactionBuilder.build();  
SignedTransaction stx = Account.signLogicsigTransaction(lsig, paymentTransaction);  
transactionEnvelope.setSignedTransaction(stx);

```
    ByteArrayOutputStream byteOutputStream = new ByteArrayOutputStream();
    for (TransactionEnvelope transactionEnvelope : transactionGroup.getTransactionEnvelopeList())
    {
    String teId = transactionEnvelope.getId();

    TransactionEnvelope actual = this.transactionEnvelopeMap.get(teId);
    byte[] transactionBytes = Encoder.encodeToMsgPack(actual.getSignedTransaction());
    byteOutputStream.write(transactionBytes);

    log.info("Submitting transaction: " + actual.getSignedTransaction().transactionID);

    }

    String[] headers = {"X-API-Key"};
    String[] values = {"xI8HYsARcd9qQDfJCmFh39AfRNWu1f8hMZmC5ky5"};
    String[] txHeaders = ArrayUtils.add(headers, "Content-Type");
    String[] txValues = ArrayUtils.add(values, "application/x-binary");
    byte groupTransactionBytes[] = byteOutputStream.toByteArray();

    com.algorand.algosdk.v2.client.common.AlgodClient algodv2Client = getAlgodClientV2();
    RawTransaction rawTransaction = algodv2Client.RawTransaction();
    rawTransaction.rawtxn(groupTransactionBytes);
    Response<PostTransactionsResponse> response = rawTransaction.execute(txHeaders,txValues);
    System.out.println("reponse"+response);
    PostTransactionsResponse id = response.body();
    transactionGroup.setAlgorandTransactionId(id.txId);
    log.info("successfully committed group transaction with transaction id " + id.txId + " " + transactionGroup);
    waitForIndividualGroupTransactions( transactionGroup);
    return id.txId;

```

Getting Null Response in rawTransaction.execute(txHeaders,txValues).body().
