Map has spikes on terrain mapping

I've implemented a terrain mapping feature on my MapBox map, but it is showing spikes when in production.

My code -

// 3D Terrain source
this.map.addSource('mapbox-dem', {
  'type': 'raster-dem',
  'url': 'mapbox://mapbox.mapbox-terrain-dem-v1',
  'tileSize': 512,
});
 
// add the DEM source as a terrain layer with exaggerated height
this.map.setTerrain({
  'source': 'mapbox-dem',
  'exaggeration': 1
});
