Clojure: using ragtime with sqlite3 - jdbc

Question

I'd like to use ragtime to manage migrations on an SQLite database. Following the instructions here, i've tried the following in the REPL:
(require '[ragtime.jdbc :as jdbc]
'[ragtime.repl :as repl])
(def config
{:datastore (jdbc/sql-database {:connection-uri "jdbc:sqlite:resources/db.sqlite3"})
:migrations (jdbc/load-resources "migrations")})
(repl/migrate config)
All I get is the following error:
ClassCastException clojure.lang.PersistentVector cannot be cast to clojure.lang.Named clojure.core/name (core.clj:1546)
The database file exists in resources/db.sqlite3. I've tried tracing the exception (i can add the stack trace if needed), but it seems to happen deep in clojure.java.jdbc.
As I'm new to the JVM and JDBC, I'm also not sure whether I'm specifying the :connection-uri correctly; I've tried several variants but can't seem to make it worK.
Any help would be much appreciated !
EDIT: stack trace:

(the rest is REPL and compiler calls)
And the two migration files, resources/migrations/001-initial.up.sql:
CREATE TABLE tests (
id INTEGER PRIMARY KEY AUTOINCREMENT
);
and resources/migrations/001-initial.down.sql:
DROP TABLE tests;

Give it a go with these versions:
[org.clojure/java.jdbc "0.6.1"]
[org.xerial/sqlite-jdbc "3.8.7"]
