webpage returns 405 status code error when accessed with scrapy

问题

I am trying to scrap below URL with scrapy -

https://www.realtor.ca/Residential/Single-Family/18279532/78-80-BURNDEAN-Court-Richmond-Hill-Ontario-L4C0K1-Westbrook#v=n

but, It always ends up giving status 405 error. I have searched about this topic but they always say that it occurs when the request method is incorrect, like POST in place of GET. But this is surely not the case here.

here is my code for spider -

import scrapy

class sampleSpider(scrapy.Spider):
    AUTOTHROTTLE_ENABLED = True
    name = 'test'
    start_urls = ['https://www.realtor.ca/Residential/Single-Family/18279532/78-80-BURNDEAN-Court-Richmond-Hill-Ontario-L4C0K1-Westbrook#v=n']

    def parse(self, response):


        yield {
            'response' : response.body_as_unicode(),
        }

and here is the log I get when I run the scraper -

Any help will be very much appreciated. Thank you in advance.

I encountered a similar problem trying to scrape www.funda.nl and solved it by

changing the user agent (using https://pypi.org/project/scrapy-random-useragent/),
using Scrapy Splash.

This may work for the website you're trying to scrape as well (although I haven't tested this).
