413 ERROR for this type of fetch

[xanderjakeq]

notifs = await Notification.fetchList({
            offset,
            limit,
            author: {
                $ne: username
            },
            listId: listIds,
            sort: '-createdAt'
        });

Where listIds is an array
This should fetch Notification models with listId values that are in the listIds array.

Is there a limit to how long the listIds array is?

I'm currently having a problem where it's giving me 431 error when the length of listIds array is greater than or equal to 160.

Is there a better way to query Notifications? or a workaround for this?

[xanderjakeq]

This is the solution I came up with.

1. chunk listIds to subarrays with a length shorter than 160 (I settled with 100)
2. for each chunk, do a fetchList.
3. flatten the result
4. sort the flattened results

const chunked_listIds = chunk(listIds, 100);

const chunked_notifs = await Promise.all(chunked_listIds.map( async (chunk) => {
		return await Notification.fetchList({
				offset,
				limit,
				author: {
					$ne: username
				},
				listId: chunk,
				sort: '-createdAt'
			});
		}));

 const _notifs = chunked_notifs.flat();
 const notifs = _notifs.sort()

do let me know if there is a better way! :)
