Cannot read properties of undefined (reading 'length') Lottie React

Question

I get an undefined issue while trying to set lotties using lottie-react I am setting CDN link instead of just importing it directly . This is the code :

{missions.map((mission : any) => 
   (
<div className='bg-[#000000] flex-1'>
<Lottie animationData={mission?.manuscript?.asset.url} loop={true} />
</div>
   )}

Eventually I get an issue of Cannot read properties of undefined (reading 'length')

  577 |               var layerData;
  578 |               var i;
> 579 |               var len = layers.length;
  580 |               var j;
  581 |               var jLen;
  582 |               var k;

{mission?.manuscript?.asset.url} is not undefined ! Any idea how to solve this ?
