What is the wrong in my integration flow and tasklet - spring-integration

Question

This is my flows LS-GET(SFTP outbound gateway: download files from a remote SFTP server.)
and MessagingGateway.
#MessagingGateway
public interface IntegratedRemoteFileProcessMessagingGateway {
#Gateway(requestChannel = "getFlows.input")
void getFlows(final String remoteDirectory);
#Gateway(requestChannel = "moveFlows.input")
void moveFlows(final String remoteDirectory);
}
#Bean
public QueueChannelSpec getOutputChannel() {
return MessageChannels.queue();
}
#Bean
public IntegrationFlow getFlows() {
return f -> f
.enrichHeaders(h -> h
.headerExpression("originalPayload", "payload.toString()")
.headerExpression(FileHeaders.REMOTE_DIRECTORY, "payload.toString()"))
.log(LoggingHandler.Level.INFO, "eu.haee", "'Header originalPayload=' + headers[originalPayload]")
.handle(Sftp.outboundGateway(sessionFactory, Command.LS.getCommand(), "payload")
.autoCreateDirectory(false)
.autoCreateLocalDirectory(false)
.charset("UTF-8")
.filter(new SftpSimplePatternFileListFilter("*.xml"))
.options(Option.NAME_ONLY, Option.RECURSIVE))
.split()
.log(LoggingHandler.Level.INFO, "eu.haee", "'LS Payload= ' + payload.toString()")
.enrichHeaders(h -> h
.headerExpression("originalRemoteFile", "payload.toString()")
.headerExpression(FileHeaders.REMOTE_FILE, "payload.toString()"))
.handle(Sftp.outboundGateway(sessionFactory, Command.GET.getCommand(), "headers['originalPayload'] + headers['file_remoteFile']")
.autoCreateLocalDirectory(false)
.charset("UTF-8")
.fileNameExpression("headers['file_remoteFile']")
.localDirectory(new File(flowsConfiguration.localDirectory()))
.localFilenameExpression(new FunctionExpression<Message<?>>(m -> {
IntegrationMessageHeaderAccessor accessor = new IntegrationMessageHeaderAccessor(m);
final String remoteFileName = (String) accessor.getHeader("file_remoteFile");
final int extensionIndex = remoteFileName.lastIndexOf('.');
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMddHHmmss.SSSSS", Locale.GERMAN);
return String.format("%s_MYC(%s-%d)%s", remoteFileName.substring(0, extensionIndex),
ZonedDateTime.of(LocalDateTime.now(), ZoneId.of("Europe/Berlin")).format(formatter),
(new SecureRandom()).nextInt(99999),
remoteFileName.substring(extensionIndex));
}))
.options(Option.PRESERVE_TIMESTAMP)
.remoteFileSeparator("/"))
.channel("getOutputChannel");
}
This is my spring-batch tasklet and Junit. MessagingGateway injected via tasklet constructor.
#Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
for (Endpoint endpoint : endpoints) {
final String remoteDirectory = endpoint.getEpConUri();
logger.info("ProcessRemoteFilesFlowsTasklet {} dealer at {} remote files process starting",
endpoint.getId().getDlrCd(), remoteDirectory);
flowsMessagingGateway.getFlows(remoteDirectory);
}
return RepeatStatus.FINISHED;
}
#Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
controlChannel.send(new GenericMessage<>("#getPoller.start()"));
logger.info("GetPollerRemoteFilesFlowsTasklet poller starting...");
return RepeatStatus.FINISHED;
}
#Autowired
private IntegratedRemoteFileProcessMessagingGateway flowsMessagingGateway;
#Autowired
private EndpointRepository endpointRepository;
#Test
public void getFlows() {
flowsMessagingGateway.getFlows("/c07va00011/iris/import/");
Uninterruptibles.sleepUninterruptibly(60, TimeUnit.SECONDS);
}
When I execute getFlows test code. I met exception. but file downloaded to my local computer.
I have no idea. I've tried many variants but didn't get any progress.

#EnableIntegration placed every spring-integration related configuration classes. #IntegrationComponentScan also placed my main flow configuration class (with string arrays of package names to scan).
If #EnableIntegration annotation located in multiple classes what happens?
Should I merge all spring-batch and spring-integration configuration classes into one?
Also, I've tested ControlBus(Send messages to the poller in the spring-batch tasklet) and got the same exception.
