[BUG 🐛] contours is always empty using contourMode: "all"

Describe the bug:

I tried to get contours of a face using contourMode: "all" in FaceDetectionOptions but I always got an empty object:

 [
  {
    "bounds": {
      "height": 409,
      "width": 409,
      "x": 43,
      "y": 412
    },
    "contours": {},
    "leftEyeOpenProbability": 0.9938164353370667,
    "pitchAngle": 12.616621017456055,
    "rightEyeOpenProbability": 0.9974306225776672,
    "rollAngle": -2.7283248901367188,
    "smilingProbability": 0.0071668741293251514,
    "yawAngle": -10.873421669006348
  }
]

Expected behavior:

I was hopping to get contours point as in ML Kit documentation

I have tryed: Playing with different parameters landmarkMode none/all, trackingEnabled: true/false, performanceMode: accurate/false, etc. EDIT : Since, I tried to force the GoogleMLKit dependency in the podspec file (5.0 & 4.0) but still have the same issue. I ran my app using Xcode and I add some debug log in VisionCameraFaceDetector.swift and face.contours is indeed empty. Everything looks good in FaceDetectorOptions So it's really weird.
