golang viant dsunit testing config error

when trying to setup my Db using ds http://ift.tt/2cQfXnM I am using the following config

{
  "DatastoreConfigs": [
    {
      "Datastore": "db_test",
      "AdminDbName": "mysql",
      "ClearDatastore": true,
      "ConfigUrl": "test://config/dbconfig.json",
      "Descriptors": null
    },
    {
      "Datastore": "mysql",
      "ConfigUrl": "test://test/admin.json"
    }
  ]
}

And I get this error. Any idea what I am missing ?
