It looks like a bug in Drift. Try adding an init function which takes
one argument but doesn't do anything.
Your new migrate-config should look something like:
(defn migrate-config []
{:init (fn [_] )
:directory "/db/migrations"
:current-version db-version
:update-version update-db-version})
Let me know if that does the trick and I'll fix the bug in Drift.
