I’m trying to implement pagination for entries that are in an array, but I can’t seem to get any results.

*[_type == 'market' && siteDomain == "<http://www.website.se|www.website.se>"][0] {
  'tripCollections': tripCollections[@->nameSv in ["Spain"]] -> {
    'name': @.['nameSv'],
    'trips': trips[_id > "trip-17058401-3baa-40cf-8fc9-11869112b117"] | order(_id) [0...3] -> {
      _id,
      recipe,
      'images': images[]->image.asset->url,
      'headline': contentSv->headline,
      'salesPitch': contentSv->salesPitch,
      'slug': contentSv->slug
    }
  }
}


trips[_id > "trip-17058401-3baa-40cf-8fc9-11869112b117"] | order(_id) [0...3]
contains the _id of the very first item in the array of elements, then I try to fetch 0 to 3.
But for some reason I just get an empty result.
Is there anything obvious that I’m doing wrong?

If it wasn’t clear already, 
trips
is an array. Also not sure if it matters but the order of the elements are important to me, I wish to preserve them the way they are in listed in the CMS.
Also important to note that the array is an array of references

OK, I figured out what the problem was. The problem was that I had to do pagination based on the 
_ref
property instead of 
_id
, because 
_id
only appears after the dereference.

Here’s the updated query if anyone’s interested.

*[_type == 'market' && siteDomain == "<http://www.website.se|www.website.se>"][0] {
  'tripCollections': tripCollections[@->nameSv in ["Spain"]] -> {
    'name': @.['nameSv'],
    'trips': trips[_ref > "trip-17058401-3baa-40cf-8fc9-11869112b117"] | order(_ref) [0...3] -> {
      recipe,
      'images': images[]->image.asset->url,
      'headline': contentSv->headline,
      'salesPitch': contentSv->salesPitch,
      'slug': contentSv->slug
    }
  }
}
