Hyperledger Fabric: unknown service orderer.AtomicBroadcast on channel.sendTransaction() - hyperledger-fabric

Question

i'm new to the fabric world and i'm testing the Java SDK in Fabric 1.4.
I've already set up a smart contract through Visual Studio Code and the fabric local env.
Now, I want to interact with it calling a smart contract endpoint via Java.
private Optional<FileAsset> sendTransaction(HFClient client, String functionToCall, String... args) {
Channel channel = client.getChannel(channelName);
TransactionProposalRequest tpr = TransactionProposalRequest.newInstance(client.getUserContext());
ChaincodeID fileChainCCId = ChaincodeID
.newBuilder()
.setName(chaincodeName)
.setVersion(chaincodeVersion)
.build();
tpr.setChaincodeID(fileChainCCId);
tpr.setChaincodeLanguage(Type.NODE);
tpr.setFcn(functionToCall).setArgs(args);
tpr.setProposalWaitTime(6_000);
log.info("Calling function: {} with args: {}", functionToCall, args);
Map<String, byte[]> tm2 = new HashMap<>();
tm2.put("HyperLedgerFabric", "TransactionProposalRequest:JavaSDK".getBytes(UTF_8)); // Just
tm2.put("method", "TransactionProposalRequest".getBytes(UTF_8)); // ditto
tm2.put("result", ":)".getBytes(UTF_8)); // This should be returned in
// the payload see chaincode
// why.
tm2.put(EXPECTED_EVENT_NAME, EXPECTED_EVENT_DATA); // This should
// trigger an event
// see chaincode
// why.
try {
tpr.setTransientMap(tm2);
} catch (InvalidArgumentException e) {
log.error("Error setting transient map. Err: {}", e.getMessage());
return Optional.empty();
}
Collection<ProposalResponse> responses = null;
try {
responses = channel.sendTransactionProposal(tpr, channel.getPeers());
} catch (ProposalException | InvalidArgumentException e) {
log.error("Error sending transaction proposal: {}. Err: {}", tpr, e.getMessage());
return Optional.empty();
}
List<ProposalResponse> invalid = responses.stream().filter(r -> r.isInvalid()).collect(Collectors.toList());
if (!invalid.isEmpty()) {
invalid.forEach(response -> {
log.error(response.getMessage());
});
return Optional.empty();
}
List<ProposalResponse> resps = responses.stream()
.filter(r -> r.getStatus().equals(ProposalResponse.Status.SUCCESS)).collect(Collectors.toList());
resps.stream().forEach(resp -> {
log.info("Successful transaction proposal response Txid: {} from peer {}", resp.getTransactionID(),
resp.getPeer().getName());
});
try {
Collection<Set<ProposalResponse>> proposalConsistencySets = SDKUtils.getProposalConsistencySets(responses);
if (proposalConsistencySets.size() != 1) {
log.error("Expected only one set of consistent proposal responses but got {}",
proposalConsistencySets.size());
return Optional.empty();
}
} catch (InvalidArgumentException e) {
log.error("Error generating proposal consistency sets. Err: {}", e.getMessage());
return Optional.empty();
}
// If all responses are fine, then we can proceed with sending the
// transaction to an orderer
CompletableFuture<TransactionEvent> sentTransaction = channel.sendTransaction(resps, channel.getOrderers(), client.getUserContext());
// For simplicity, we just request result with a timeout and verify that
// for validity.
BlockEvent.TransactionEvent event = null;
try {
event = sentTransaction.get(60, TimeUnit.SECONDS);
} catch (InterruptedException | ExecutionException | TimeoutException e) {
log.error("Error sending transaction to orders. Err: {}", e.getMessage());
return Optional.empty();
}
if (event.isValid()) {
log.info("Transacion tx: " + event.getTransactionID() + " is completed.");
} else {
log.error("Transaction tx: " + event.getTransactionID() + " is invalid.");
}
return Optional.empty();
}
On
CompletableFuture<TransactionEvent> sentTransaction = channel.sendTransaction(resps, channel.getOrderers(), client.getUserContext());
I get the following error:

Any suggetions about how to resolve it?

Answer 1

You are targeting a peer for AtomicBroadcast - peer0.org1.example.com
you need to target an orderer. seems like your network configuration is wrong.
