GROQ - Subquery with Dereferencing Issue

1 replies
Last updated: Jun 21, 2022
is there a known bug with regard to a query like this?

*[
  _type == 'celeb' &&
  count(*[
    _type == 'fact' &&
    '9171bdb4-1a9b-4cb0-a967-211790a44073' in tags[].tag->_id &&
    celeb._ref == ^._id
  ]) > 0
]
I'm trying to get 
celebs
that have a 
fact
, where one of the 
facts
has a 
tag
of a certain ID.
My "bug" is in this line 
'9171bdb4-1a9b-4cb0-a967-211790a44073' in tags[].tag->_id
. If I replace that line with a simple condition that doesn't have further de-referencing, it works as expected. The query inside 
count
also works as expected when it is a stand-alone query. It just doesn't work (i.e. returns an empty array) when it is used a subquery.
I'm wondering if I'm experiencing the same issue described
here .

I just found out that if I simply change 
tag->_id
to 
tag._ref
the query will work

*[
  _type == 'celeb' &&
  count(*[
    _type == 'fact' &&
    '9171bdb4-1a9b-4cb0-a967-211790a44073' in tags[].tag._ref &&
    celeb._ref == ^._id
  ]) > 0
]
