if you are expecting nested inputs, it is only available in pathom3 https://pathom3.wsscode.com/docs/resolvers/#nested-inputs

About missing-output:

(let [a (pco/resolver `a
          {::pco/output [:a]}
          (fn [_ _]
            ;; :com.wsscode.pathom3.error/missing-output
            ;; when a resolver say that it will return :a, but dont
            {}))
      env (pci/register [a])]
  (try
    (p.eql/process env [:a])
    (catch Throwable ex
      (:com.wsscode.pathom3.error/cause (:com.wsscode.pathom3.error/error-data (ex-data ex))))))
  

@U2J4FRT2T that sounds the same as "output didn't include the attribute", no? What bit of nuance am I missing?

Is it for when the whole output is missing?

I'm trying to create a :com.wsscode.pathom3.error/attribute-missing error in my repl

they work at different times, attribute missing is more broad, means attribute was expected by query, but wasn't there, this check runs after the graph is done for given entity, makes sense?

@U066U8JQJ so attribute-missing can happen during the graph traversal, whereas missing-output only happens at the end?

humm, I'm doing a double check reading the code, I'm starting to think one of them might not happen, because they are in the two different places, aparently for the same reason

I can't go deep check now, but I'll open an issue to clear this up

Okay, thank you. I do believe I've actually encountered both errors during development, but I don't have a repro at the moment.. I could be mistaken. If it comes up again I will document it somewhere and leave a link here.
