Is it possible to create some route for javascript challenged protected site?

[affhp]

For example, https://pulsehknews.com/c/%e8%b2%a1%e7%b6%93%e7%af%80%e7%9b%ae/simon-lee-financial-insights/
This is a site protected by Deflect, I guess it is just like Cloudflare protection.
In browser inspection, it seems required deflect_challenge cookies which is not reusable, i.e., cannot use it later even in curl in my test.

The most ridiculous thing is that the site already have RSS built-in, but I cannot use that because of the protection. So I am trying to use RSSHub puppeteer to do it myself.

However In my test even puppeteer does not work, which also throw Error: this route is empty error.

Since the site already have RSS built-in, I would also want to know if there are any possible ways to bypass the protection and get those rss feed for some RSS clients like FreshRSS.

Thanks!
