I’m sure I’m missing something, but does anyone know what might be causing this? (It’s fine locally, but it fails on a EC2 instance)

I added this EC2 to the same VPC as Datomic Cloud - I’m not sure this is the way to go, I’m trying to figure things out.

I added an SSH inbound rule, but that’s it, I didn’t mess with any other configuration.

(Clojure CLI version 1.10.3.855)

I create entities like so and put some values in those entities. So far there are no errors:

(d/transact conn [{:db/ident :carecoach/name
   :db/valueType :db.type/string
   :db/cardinality :db.cardinality/one
   :db/unique :db.unique/identity
   :db/doc "name"}
  {:db/ident :carecoach/number
   :db/valueType :db.type/long
   :db/cardinality :db.cardinality/many
   :db/unique :db.unique/identity
   :db/doc "number"}
  ])

(d/transact conn [{:carecoach/name "Prikshet" :carecoach/number 20}])

(d/transact conn [{:carecoach/name "Deepak" :carecoach/number 10}])

(d/transact conn [{:carecoach/name "Prikshet" :carecoach/number 30}])

(d/transact conn [{:carecoach/name "Deepak" :carecoach/number 20}])

(d/transact conn [{:carecoach/name "Prikshet" :carecoach/number 40}])

(d/transact conn [{:carecoach/name "Deepak" :carecoach/number 50}])

(defn get-sum [name-string]
  (d/pull db '[*] [:carecoach/name name-string])
  #_(d/q '[:find ?number
         :in $ ?name-string
         :where
         [?e :carecoach/name ?name-string]
         [?e :carecoach/number ?number]
         ]
       db name-string)
  )

(get-sum "Deepak")
