clojure - Datomic valueType -

when trying persist list of node entities :threshold attribute defined in schema:

{:db/id #db/id[:db.part/db]  :db/ident :node/threshold  :db/valuetype :db.type/long  :db/cardinality :db.cardinality/one  :db/fulltext false  :db/doc "threshold"  :db.install/_attribute :db.part/db} 

i following error:

compilerexception java.util.concurrent.executionexception:  java.lang.illegalargumentexception:  :db.error/wrong-type-for-attribute value 90 not valid :int  attribute :node/threshold 

i use following code:

(defn store-tree [tree]   @(d/transact dbconn/conn (into [] (vals tree)))) (store-tree parsed-tree-with-refs) 

where tree map of node names nodes.

curiously enough, took edn specific entity :node threshold 90 repl , manually transact'ed it, , worked without problems. used code:

@(d/transact dbconn/conn [{:db/id (d/tempid :db.part/user),   :node/threshold 90, :node/location "us"}]) 

can please help?

thanks, vitaliy.
