Hey there!
I am trying to create some custom queries for my daily journals but I am facing some issues. I am trying to fetch all the undone tasks tagged with the page “urgent”. However it’s not showing any result. This is the query:

#+BEGIN_QUERY 
{
:query 
[
  :find (pull ?b [*])
  :in $ ?today
  :where
  (task ?b #{"LATER" "DOING" "WAITING" "NOW"})
  (page ?b #{"urgent"})
]
:inputs [:today]
}
#+END_QUERY

Thanks
