gltf piepeline draco compression creates weird edges

Question

I'm trying to compress a glb file with gltf pipeline module ( https://github.com/CesiumGS/gltf-pipeline )

The original glb file looks like the following:

I'm compressing glb model with the following script:

const getCompressedGltfFile = async (glb) => {
  try {
    const compressedFile = await processGlb(glb, {
      dracoOptions: {
        compressionLevel: 10,
      },
    });
    return compressedFile.glb;
  } catch (error) {
    console.log("compressingGltfFile failed:", glb, error);
    return glb;
  }
};

Is there any way I can compress glb model without creating weird edges?
