nil is not a symbol nor a string - ruby-on-rails

Question

Im trying to use Kimurai to scrape a website. Im running into this error when I want to do /scrape.
def scrape
url = "https://www.tripadvisor.com/Restaurants-g31892-Rogers_Arkansas.html"
response = RestaurantsScraper.parse!(response, url, data: {})
if response[status] == :completed && response[error].nil?
flash.now[notice] = "Successfully scraped url"
else
flash.now[alert] = response[error]
end
end
Here is my scraper class
class RestaurantsScraper < Kimurai::Base
#name = "restaurants_scraper"
#driver = :selenium_chrome
#start_urls = ["https://www.tripadvisor.com/Restaurants-g31892-Rogers_Arkansas.html"]
def parse(response, url:, data: {})
response.xpath("//div[#class=_1llCuDZj]").each do |a|
request_to :parse_repo_page, url: absolute_url(a[:href], base: url)
end
end
def parse_repo_page(response, url:, data: {})
item = {}
item["title"] = t.css('a._15_ydu6b')&.text&.squish&.gsub('[^0-9].', '')
item["type"] = t.css('span._1p0FLy4t')&.text&.squish
item["reviews"] = t.css('span.w726Ki5B').text&.squish
item["top_reviews"] = t.css('a._2uEVo25r _3mPt7dFq').text&.squish
Restaurant.where(item).first_or_create
end
end
Here is the error im getting

It's because response from RestaurantsScraper.parse!(response, url, data: {}) isn't defined.
From the kimurai docs it says you need to pass a Nokogiri::HTML::Document object.
I haven't used Kimurai and it feels like there is definitely a better way to do this, but something like the following may be enough to get you to the next step:
def scrape
require 'open-uri'
url = "https://www.tripadvisor.com/Restaurants-g31892-Rogers_Arkansas.html"
html = Nokogiri.parse open(url)
response = RestaurantsScraper.parse!(html, url, data: {})
if response[status] == :completed && response[error].nil?
flash.now[notice] = "Successfully scraped url"
else
flash.now[alert] = response[error]
end
end
