Attempting to transact schema to a Datomic Cloud DB, getting the following exception: ```auto clojure.core/eval core.clj: 3206 ... compute.db.core_test$eval21762.invoke : 1 compute.db.core_test$eval21762.invokeStatic : 1 datomic.client.api/eval3011/fn/G api.clj: 127 datomic.client.api.sync/eval20111/fn sync.clj: 89 datomic.client.api.sync/ares sync.clj: 30 clojure.core/ex-info core.clj: 4739 clojure.lang.ExceptionInfo: Value of :db.install/attribute must be in :db.part/db partition, found :workload/maximum-instances a: :db.install/attribute cognitect.anomalies/category: :cognitect.anomalies/incorrect cognitect.anomalies/message: "Value of :db.install/attribute must be in :db.part/db partition, found :workload/maximum-instances" db/error: :db.error/not-in-system-partition dbs: [{:database-id "382aa9d2-245d-4a00-b432-12e1310f7f90", :t 5, :next-t 6, :history false}] v: :workload/maximum-instances ``` The attribute associated with the exception varies with different calls. The example in Getting Started seems to work, though if I fiddle around with it failures sometimes occur, but with no reliable repro. Schema below. This works fine with on-prem. ```auto [#:db{:valueType :db.type/uuid, :cardinality :db.cardinality/one, :ident :compute.data-model.command/id, :unique :db.unique/identity} #:db{:valueType

Update: seems to work as long as the `:db/ident` is the “first” entry in the attribute definition map, e.g. ```auto (d/transact conn (mapv #(into (select-keys % [:db/ident]) %) schema)) ``` ---

I just ran into this as well. Here’s a minimal example: ```clojure (let [conn (d/connect client {:db-name "foo"})] (d/transact conn {:tx-data [#:db{:valueType :db.type/instant, :cardinality :db.cardinality/one, :ident :foo/bar}]})) clojure.lang.ExceptionInfo: Value of :db.install/attribute must be in :db.part/db partition, found :foo/bar ``` As @sparkofreason said, if you move `:db/ident` to be the first key in the map, it works. ```clojure (let [conn (d/connect client {:db-name "foo"})] (d/transact conn {:tx-data [#:db{:ident :session/last-used-on :valueType :db.type/instant, :cardinality :db.cardinality/one}]})) => {:db-before {:database-id "ae464fcb-0bc3-48f3-b3a4-3c8e9eff1d5a", :db-name "foo", :t 3, :next-t 4, :type :datomic.client/db}, :db-after {:database-id "ae464fcb-0bc3-48f3-b3a4-3c8e9eff1d5a", :db-name "foo", :t 4, :next-t 5, :type :datomic.client/db}, :tx-data [#datom[13194139533316 50 #inst"2018-10-18T18:08:00.642-00:00" 13194139533316 true] #datom[64 10 :foo/bar 13194139533316 true] #datom[64 40 25 13194139533316 true] #datom[64 41 35 13194139533316 true] #datom[0 13 64 13194139533316 true]], :tempids {}} ``` After asking in #datomic in on Clojurians Slack, @marshall said this is a bug in Datomic and he would pass it along to the team.
