The example extract-and-fill-forms doesn't work.

[fixapi-org]

I tried this example:
https://github.com/x4nth055/pythoncode-tutorials/tree/master/web-scraping/extract-and-fill-forms

But failed.

I add res.raise_for_status() after the line calling session.post.
The error is:

The website for test is Wordpress based.
How can we fix it?
Thanks for your advice in advance.

I've just found the authors repo and using some of these features, which are very handy.

Wordpress is such a constant briar patch and tar pit of bad design, that its almost never a good idea, good solution or anything more than a "look what I did" over the weekend for beginners. Try testing on another site, or if you figure it out post here and I'll help update this with @x4nth055 permission.

Thank you for your response.
But, actually, I didn't use WP to test the example I mentioned above.

@fixapi-org so when you say You didn't use WP... both you and your stack trace kinda indicates otherwise
wp-comments and the whole "the website for test is wordpress based"

/wp-comments-post.php (Caused by ProxyError('Cannot connect to proxy.', OSError(0, 'Error')))
