Clojurians Log v2

With the following code I try to identify for each team who is the oldest person in the team. It does not work. I have no experience with Datomic, so I am struggling a bit. I understand the documentation of Datomic so that I can use the max function inside a query and not only inside the :find expression. Is this correct, and does this also work in Datalevin? (using Datalevin 0.9.22)

(def my-db
  (d/get-conn "test/svn_test_db" {:age {:db/valueType :db.type/long}}))

(d/transact my-db [{:name "Peter" :age 24 :team "a"}
                   {:name "Sandra" :age 46 :team "a"}
                   {:name "Hank" :age 23 :team "b"}
                   {:name "Emily" :age 2 :team "b"}])

(d/q '[:find ?team ?name ?highest-age
       :where
       [?oldest :name ?name]
       [?oldest :team ?team]
       [?oldest :age ?highest-age]
       [?member :team ?team]
       [?member :age ?age]
       [(max ?age) ?highest-age]]
     (d/db my-db))
=>
#{["a" "Peter" 24]
  ["b" "Emily" 23]
  ["b" "Hank" 23]
  ["a" "Sandra" 24]
  ["a" "Sandra" 46]
  ["a" "Peter" 46]
  ["b" "Hank" 2]
  ["b" "Emily" 2]}
