Scrapy can't open this URL? `response` is None

When I run these commands...

scrapy shell "https://brpurch.ionwave.net/CurrentSourcingEvents.aspx"
view(response)

I get this error...

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/home/me/ENV/stuff/local/lib/python2.7/site-packages/scrapy/utils/response.py", line 70, in open_in_browser
    body = response.body
AttributeError: 'NoneType' object has no attribute 'body'

How do I parse this page in Scrapy?

My browser is Chromium v67.0.3396.87. My OS is Debian 9.3.

Here's the full output when I run scrapy shell, before view(response).

You have ROBOTSTXT_OBEY=True (default value) in your settings.py file and scrapy shell reads this value and use it.

You can try this command: scrapy shell https://brpurch.ionwave.net/CurrentSourcingEvents.aspx --set="ROBOTSTXT_OBEY=False"

I can see the message 'Forbidden by robots.txt'.

Maybe just edit ROBOTSTXT_OBEY=False in your setting.

Similar answer can be found on SO: getting Forbidden by robots.txt: scrapy

I can't reproduce it - I used the same commands you type and it works fine here. I can see the answer in the browser. Do you get more output? Maybe a traceback? Edit the question and put the full output please.
