news not loading

app try to get url:
https://material.uplabs.com/posts/c/resources?page=2

but site return full HTML page
can you fix this for demo? or tell me please answer format

and app crash
for this you need to write:
private void getRandomCover(List items) {
if (items.size() >0) {
Item item = items.get(new Random().nextInt(items.size()));
UpRequests.getItemImage(item.getId(), this);
}
}

Reproduce the request to https://material.uplabs.com/posts/c/resources?page=2 and inspect how its full HTML response is handled. Trace the getRandomCover method and the UpRequests.getItemImage(item.getId(), this) call to locate the crash. Done means the news response has a supported format and the app no longer crashes when loading it.
