Items not returned in scrapy cloud

Hi all,

Sorry if this is a silly question. 

I'm not getting any items returned when I run the spider on scrapy cloud. It works fine on my local machine.

spider.py file

import scrapy
from ..items import AmazonItem

class AmazonSpiderSpider(scrapy.Spider):
    name = 'amazon_reviews'
    domain = 'https://amazon.com.au/'
    asin = 'B07KSCJNPB'
    product = 'LOr-Espresso-Coffee-Lungo-Estremo'
    start_urls = [domain+product+'/product-reviews/'+asin]

    def parse(self, response):
        items = AmazonItem()
        reviews = response.xpath("//div[@class='a-section review aok-relative']")
        review_asin = self.asin
        review_product = self.product

        for review in reviews:
            review_rating = review.css('.review-rating').css('::text').extract()
            review_title = review.css('.a-text-bold span').css('::text').extract()
            review_date = review.css('.review-date').css('::text').extract()
            review_text = review.css('.review-text-content span').css('::text').extract()

            items['review_rating'] = review_rating
            items['review_title'] = review_title
            items['review_date'] = review_date
            items['review_text'] = review_text
            items['review_asin'] = review_asin
            items['review_product'] = review_product

            yield items

            next_page = response.css('li.a-last a::attr(href)').get()

            if next_page is not None:
                yield response.follow(next_page, callback=self.parse)

setting.py

# See also autothrottle settings and docs
DOWNLOAD_DELAY = 3

# Disable cookies (enabled by default)
COOKIES_ENABLED = False

DOWNLOADER_MIDDLEWARES = {
    'scrapy.downloadermiddlewares.useragent.UserAgentMiddleware': None,
    'scrapy_user_agents.middlewares.RandomUserAgentMiddleware': 400,
}

# Enable and configure the AutoThrottle extension (disabled by default)
# See https://docs.scrapy.org/en/latest/topics/autothrottle.html
AUTOTHROTTLE_ENABLED = True

I have tried enabling and disabling the auto-throttle. It returned items the first time I disabled however has stopped retuning items since. 

The log file is
