Hmm, I think I tried to fix this for comments here: 9054d3c but didn't know it happens for stories too. If for comments, I feel that it's fine that one or two of them fails and "missing" from the response. But for stories... that's kinda weird 😕 especially when the API response looks like [STORY, STORY, null, STORY, STORY, ...].

Probably would be better to remove the null from the array?

I have handled it just by checking whether Item is nulll of not as below
Promise.all(itemFetches).then(function(res){
var apiRes = res.map(function(item){
if (item) { <--- Added this .. and this fixed this issue for me.

I think it would be better to remove the null from the array.

I was worried about [STORY, STORY, null, STORY, STORY, ...], but my FE handled null properly.
