Web Scrapping from TripAdvisor with Scrapy don't extract

I'm trying to extract the all reviews from people who reviewed hotels in Bali, this should be the pathway that i'm following

1. First define the star url https://www.tripadvisor.com.pe/Hotels-g294226-Bali-Hotels.html
2. Scrapy the pages from all the hotels related to first link https://www.tripadvisor.com.pe/Hotels-g294226-oa30-Bali-Hotels.html (every page change -oaXX-)
3. Obtain the reviews from each hotel in each page from the hotel https://www.tripadvisor.com.pe/Hotel_Review-g3404940-d1532277-Reviews-Munduk_Moding_Plantation_Nature_Resort_Spa-Gobleg_Banjar_Buleleng_Regency_Bali.html
4. Scrapy on the pages from the opinions from each hotel https://www.tripadvisor.com.pe/Hotel_Review-g3404940-d1532277-Reviews-or5-Munduk_Moding_Plantation_Nature_Resort_Spa-Gobleg_Banjar_Buleleng_Regency_Bali.html#REVIEWS (every page change -orX-) 5.Access to the profile of each user who reviewed and extract all the opinions by the user https://www.tripadvisor.com.pe/Profile/AntonioPozo89?fid=6b049a76-cdf0-4534-a276-3b124769df03

the script runs but the file is empty, I'm not sure what is wrong
