Getting a 401 response when submitting form - Scrapy FormSpider

Here is the output from the scrapy log:

2019-04-19 08:17:15 [scrapy.core.engine] INFO: Closing spider (finished)

Here is my code:

from scrapy.http import FormRequest
from scrapy.spiders import Spider

class FormSpider(Spider):

    name = 'horseForm'

    start_urls = ['https://treehouse-projects.github.io/horse-land/form.html']

    def parse(self, response):
        formdata = {'firstname': 'Brian',
                    'lastname': 'Weber',
                    'jobtitle': 'Developer'}
        return FormRequest.from_response(response, formnumber=0,

    def after_post(self, response):
        print('\n\n*******\nForm processed.\n')

Note that when I try to submit the form manually here https://treehouse-projects.github.io/horse-land/form , it says that the form needs to be set up.

Yup, that's a common error running Scrapy - has to do with the way that the website is set up.

To still run the program, add these three lines to your settings.py: HTTPERROR_ALLOWED_CODES = [404] HTTPERROR_ALLOWED_CODES = [405] HTTPERROR_ALLOWED_CODES = [401]

If you want to see more information on the error, refer to this Stack Exchange post: https://stackoverflow.com/questions/48030717/scrapy-404-error-http-status-code-is-not-handled-or-not-allowed/48031332
