I am displaying a series of images hosted in CDN on my NextJS page in the "masonry layout" structure (Just like Pinterest). As shown in .
When I try to load it on my desktop it's working fine. But only when I load it on my iPhone or lower screen sizes, the screen
or it displays "A problem repeatedly occurred"() Can you please tell me how to fix it or debug it.
The code is as below for this page. All of this happens inside a [slug] folder for multi page rendering.

I think you need to change a bit in the Image component call.
change like this
{wallpaper.thumbnail_url && (<Image
src={wallpaper.thumbnail_url}
alt={wallpaper.id.toString()}
width={400} // Add fixed width
height={300} // Add fixed height
loading="lazy"
className="w-full h-auto lg:hover:scale-105 lg:transition-transform lg:duration-300"
sizes="(max-width: 640px) 45vw,
(max-width: 768px) 30vw,
(max-width: 1024px) 20vw,
15vw" // Adjusted sizes
placeholder="blur"
quality={60}
priority={false}
/>)}
and you can also add the below code on your next.config.js
images: {
deviceSizes: [640, 750, 828, 1080, 1200, 1920], // for different size of devices
imageSizes: [16, 32, 48, 64, 96, 128, 256, 384],
},
enter code here
Hope this helps.
