hey all  
I’m trying to run `import-cloud` but it fails with the error:

```auto
; Execution error (IllegalArgumentException) at datomic.dev-local.impl/fn (impl.clj:493).
; This client does not support dev-local import.

```

My setup is:  
`deps.edn`

```auto
{com.datomic/client-cloud {:mvn/version "1.0.124"}
 com.datomic/local {:mvn/version "1.0.276"}}

```

`dev.clj`

```auto
(defn sync-local []
  (let [conf (->> (io/resource "dev/config.edn")
                  slurp
                  edn/read-string)]
    (dl/import-cloud
     {:source (merge conf {:db-name "dev-itai"})
      :dest {:system "production-rep"
             :server-type :datomic-local
             :db-name "db-name"
             :storage-dir :mem}})))

```

`config.edn`

```auto
{:server-type :ion
 :region "region"
 :system "system"
 :endpoint "url"}

```

I couldn’t figure out why as I followed the [docs](https://docs.datomic.com/cloud/datomic-local.html#getting-started).  
What am I missing here?

@itaied

I think the issue here is `:storage-dir :mem` see:

```auto
(dl/import-cloud
  {:source {:system "tomhanks"
            :db-name "repodb2"
            :server-type :ion
            :region "us-east-1"
            :endpoint "https://awrqwigbi6.execute-api.us-east-1.amazonaws.com"}
   :dest {:system "tomhanks"
          :server-type :datomic-local
          :db-name "repodb2"
          :storage-dir :mem}
   })
Execution error (IllegalArgumentException) at datomic.dev-local.impl/fn (impl.clj:493).
This client does not support dev-local import.
(dl/import-cloud
  {:source {:system "tomhanks"
            :db-name "repodb2"
            :server-type :ion
            :region "us-east-1"
            :endpoint "https://awrqwigbi6.execute-api.us-east-1.amazonaws.com"}
   :dest {:system "tomhanks"
          :server-type :datomic-local
          :db-name "repodb2"}
   })
=> {:from-t 7, :tx-count 0}

```

I am confirming with the team but I do not believe you are able to import a cloud db to a `mem` DB. Our documentation certainly does not tell you that you cannot do this. And either way the error message here is outdated (mentioning dev-local vs datomic local) and unhelpful.
