Can't write grayscale HEIC image file on iOS16.2 with CGImageDestinationCreateWithData

CGImageRef grayscaleImage;
 {
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceGray();
    CGContextRef bitmapCtx = CGBitmapContextCreate(bwbuffer, width, height, 8, width, colorSpace, (CGBitmapInfo)kCGImageAlphaNone);
    grayscaleImage = CGBitmapContextCreateImage(bitmapCtx);
    CFRelease(bitmapCtx);
    CFRelease(colorSpace);
  }
UIImage *temp = [[UIImage alloc] initWithCGImage:grayscaleImage];

CFStringRef UTI= (CFStringRef)@"public.heic";
NSMutableData *newImageData = [NSMutableData data];

CGImageDestinationRef  destination = CGImageDestinationCreateWithData((__bridge CFMutableDataRef)newImageData,UTI,1,NULL);
CGImageDestinationAddImage(destination, temp.CGImage, (__bridge CFDictionaryRef)metaDataDictNew);
CGImageDestinationFinalize(destination);

This code running on iOS15. However iOS16 can't write grayscale HEIC image file.RGB image file is OK. The following were error message on console of xcode.

writeImageAtIndex:867: *** CMPhotoCompressionSessionAddImage: err = kCMPhotoError_InvalidData [-17102]  (codec: 'hvc1')

I can't find this error code in the Apple Support site also Documentation. Best regards.
