JobExecutionDecider not working with custom ExitStatus

Bug description
When we produce custom Exit status from a tasklet and use a JobExecutionDecider to decide the flow, we get an error.

Environment
Please provide as many details as possible: Spring Batch version, Java version, which database you use if any, etc
Spring Batch Version - 4.3.8
JDK - 11

Steps to reproduce
Send a custom Exit status from a taklet and use it in the JobExecutionDecider to decide the flow.

Expected behavior
The Tasklet should produce the status completed and the JobExecutionDecider should take the ExitStatus from the step and validate the status and decide on the flow.

Minimal Complete Reproducible example

@Bean
public Step initialStep() {
    return stepBuilderFactory.get("initialStep")
            .tasklet((contribution, chunkContext) -> {
                System.out.println("INTIAL STEP");
                return RepeatStatus.FINISHED;
            }).listener(stepExecutionListener()).build();
}

@Bean
public StepExecutionListener stepExecutionListener() {
    return new MyStepExecutionListener();
}

static class MyStepExecutionListener implements StepExecutionListener {

    @Override
    public void beforeStep(StepExecution stepExecution) {
        System.out.println("MyStepExecutionListener.beforeStep");
    }

    @Override
    public ExitStatus afterStep(StepExecution stepExecution) {
        var inputFileName = stepExecution.getJobParameters().getString("inputFileName");
        System.out.println("MyStepExecutionListener.afterStep");
        if (inputFileName != null && (inputFileName.contains("abc"))) {
            return new ExitStatus("YES", "For processing step");
        }
        return new ExitStatus("NO", "For failed step");
    }
}

@Bean
public JobExecutionDecider decider() {
    return (jobExecution, stepExecution) -> {
        System.out.println(stepExecution.getExitStatus().getExitCode());
        if("YES".equals(stepExecution.getExitStatus().getExitCode())) {
            return new FlowExecutionStatus("YES");
        } else {
            return new FlowExecutionStatus("NO");
        }
    };
}

Thanks!

Start with the minimal reproducer in the issue and trace how the custom ExitStatus returned by MyStepExecutionListener.afterStep reaches the JobExecutionDecider. Compare the step's exit code with the decider's flow status and verify that the expected YES or NO branch completes without the reported failure.
