Configure DDS with scrapy-splash. ERROR: no base objects - django

Question

LS,
I have installed Django-Dynamic-Scraper. And i would like to render Javascript via Splash. Therefor i have installed scrapy-splash and installed the docker splash image. The image below shows that the docker container can be reached.
Splash docker container
Nevertheless when i test it via DDS it returns the following error:
2016-10-25 17:06:00 [scrapy] INFO: Spider opened

I have configured the DDS admin page and checked the checkbox to render the javascript:
Admin configuration
I have followed the configuration from scrapy-splash:
# ----------------------------------------------------------------------
# SPLASH SETTINGS
# https://github.com/scrapy-plugins/scrapy-splash#configuration
# --------------------------------------------------------------------
SPLASH_URL = 'http://192.168.0.150:8050/'
DSCRAPER_SPLASH_ARGS = {'wait': 3}
DOWNLOADER_MIDDLEWARES = {
'scrapy_splash.SplashCookiesMiddleware': 723,
'scrapy_splash.SplashMiddleware': 725,
'scrapy.downloadermiddlewares.httpcompression.HttpCompressionMiddleware': 810,
}
# This middleware is needed to support cache_args feature;
# it allows to save disk space by not storing duplicate Splash arguments
# multiple times in a disk request queue.
SPIDER_MIDDLEWARES = {
'scrapy_splash.SplashDeduplicateArgsMiddleware': 100,
}
DUPEFILTER_CLASS = 'scrapy_splash.SplashAwareDupeFilter'
# If you use Scrapy HTTP cache then a custom cache storage backend is required.
# scrapy-splash provides a subclass
HTTPCACHE_STORAGE = 'scrapy_splash.SplashAwareFSCacheStorage'
I assume with a correct configuration of DDS/scrapy-splash, it will sends the required arguments to the splash docker container to render, Is this the case?
What am I missing? Do i need to adjust the spider with a splash script?
