What is the wrong in my integration flow and tasklet

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.

@Lazy, @DependsOn also not working. (@Lazy added to the ControlBus, @DependsOn added in the spring service class: Spring-batch jobs also manually starts/stops by rest API calls.)

These exceptions were never occurred in the spring-integration stand-alone applications.
