Huawei Hair Segmentation Retuning Null value at getMask()

Question

I'm working on a project where I have to change the hair color of a person's image and for this, I'm using Huawei Hair segmentation.

Here is the code of Analyzer which analyze the image.

val setting = MLImageSegmentationSetting.Factory()
        .setExact(true)
        .setAnalyzerType(MLImageSegmentationSetting.HAIR_SEG)
        .create()
    analyzer = MLAnalyzerFactory.getInstance().getImageSegmentationAnalyzer(setting)
    // Create an MLFrame by using android.graphics.Bitmap. Recommended image size: large than 224*224.
    bitmap = BitmapFactory.decodeResource(this.resources, R.drawable.imgseg_foreground);
    val mlFrame = MLFrame.Creator().setBitmap(bitmap).create()
    val task: Task<MLImageSegmentation> = analyzer!!.asyncAnalyseFrame(mlFrame)
    task.addOnSuccessListener(OnSuccessListener<MLImageSegmentation?> { imageSegmentationResult -> // Processing logic for recognition success.
        if (imageSegmentationResult != null) {
            [email protected](imageSegmentationResult)
        } else {
            [email protected]("imageSegmentationResult is null.")
        }
    })
        .addOnFailureListener(OnFailureListener { e -> // Processing logic for recognition failure.
            [email protected](e.message!!)
        })

And here is the code of displaySuccess()

private fun displaySuccess(imageSegmentationResult: MLImageSegmentation) {
    if (bitmap == null) {
        displayFailure("bitmap is null.")
        return
    }
    // Here I get null value in getMask()
    if (imageSegmentationResult.getMasks() == null) {
        return
    }
    var processedBitmap: Bitmap? = null
    val pixels: IntArray = byteArrToIntArr(imageSegmentationResult.getMasks())
    processedBitmap = Bitmap.createBitmap(
        pixels,
        0,
        bitmap!!.width,
        bitmap!!.width,
        bitmap!!.height,
        Bitmap.Config.ARGB_8888
    )
    if (processedBitmap != null) {
        binding.imgHolder.setImageBitmap(processedBitmap)
    } else {
        displayFailure("bitmapFore is null.")
    }
}

and I get the null value here.

if (imageSegmentationResult.getMasks() == null) {
        return
    }

This is the ml kit sdk version I'm using

// Import the base SDK.
implementation 'com.huawei.hms:ml-computer-vision-segmentation:3.4.0.300'
// Import the multiclass segmentation model package.
implementation 'com.huawei.hms:ml-computer-vision-image-segmentation-multiclass-model:3.4.0.300'
// Import the human body segmentation model package.
implementation 'com.huawei.hms:ml-computer-vision-image-segmentation-body-model:3.4.0.300'
// Import the hair segmentation model package.
implementation 'com.huawei.hms:ml-computer-vision-image-segmentation-hair-model:3.4.0.300'

And this is the log info

I don't know why it's not working as I've extracted this code from the demo app and there it's working perfectly.
