Scrapy ERROR: Spider must return Request, BaseItem or None, got 'dict'

I have tried reproducing the Scrapy tutorial using Xpath and keep running into ERROR: Spider must return Request, BaseItem or None, got 'dict' in <GET http://quotes.toscrape.com/> Not sure how to fix this.

I'm going to share snippets from two files which should be just enough for debugging:

1) My spider quotes_spider.py

from scrapy.spider import Spider
from scrapy import Request

class QuoteSpider(Spider):
    name = 'quotes'
    start_urls = [
        'http://quotes.toscrape.com/',
    ]

    def parse(self, response):
        for quote in response.xpath('//div[@class="quote"]'):
            yield {
            'text': quote.xpath('.//span[@class="text"]/text()').extract(),
            'author': quote.xpath('.//small[@class="author"]/text()').extract(),
            'tags': quote.xpath('.//div[@class="tags"]/a[@class="tag"]/text()').extract(),
            }

2) items.py

from scrapy.item import Item

class QuotesbotItem(Item):
    text = scrapy.Field()
    author = scrapy.Field()
    tags = scrapy.Field()

FYI: In case you compare this to the tutorial and are wondering why I switched the extract_first() to extract(), it's because I was seeing another error exceptions.AttributeError: 'SelectorList' object has no attribute 'extract_first' which is unrelated to this question I believe.
