Splash fails to render a specific page

[joaodjvitor]

My issue is related to querying the URL below using splash in version 3.5:

• https://leismunicipais.com.br/a/sp/s/sorocaba/decreto/2022/2738/27375/decreto-n-27375-2022-dispoe-sobre-a-revogacao-do-decreto-n-23551-de-13-de-marco-de-2018-que-dispoe-sobre-permissao-de-uso-a-titulo-precario-de-bem-publico-municipal-e-da-outras-providencias

Even after many hours, it doesn't show any results. Here are some screenshots of the execution.

I'm suffering from the same... I've tried everything, with no luck. Any thoughts?

Im experiencing similar issues, I did a test trying to render https://www.whatismybrowser.com/detect/is-javascript-enabled and Im getting that javascript isnt enabled

I've been trying to resolve this issue for two weeks now, but I still haven't made any progress. I tried changing the splash versions, I tried looking at the site prompts to see if there were any points I made mistakes, but it didn't work. I tried to use Selenium and with it the results of the page came correct, but Selenium is very slow, therefore, it does not become a viable option.

I have the same issue. I think I've narrowed it down to this script:
https://www.gstatic.com/recaptcha/releases/Km9gKuG06He-isPsP6saG8cn/recaptcha__en.js
It seems to hang on many (most? all?) pages when that script is included.

If I filter out that script, it seems to run fine. I don't know what it is about that script that Splash doesn't like, but it just hangs.

I've seen the same behavior with one other script, as well -- what appears to be a WordPress extension:
/wp-content/plugins/ninja-forms/assets/js/min/front-end.js?ver=3.6.14

It exhibits the same behavior: complete hang, but it works fine when I filter it out.

Seems likely that they're captcha check files and if they can't be loaded the site assumes to continue anyway. We could add a splash filter (similar to the easyprivacy one) that blocks common captcha checking URLs.

How do you filter it out properly? Cause I've tried some things in a script for lua_source, but it didn't work out..

I just used the request filters built into Splash. These 2 lines are fairly broad, but worked for my purposes to block the 2 scripts I mentioned:

||gstatic.com/recaptcha/
ninja-forms

As @benreece mentioned, it's most likely some script is stopping splash from loading the page. In my case, it was recaptcha script, so I used the following lua script

splash:on_request(function(request)

    if string.find(request.url, "recaptcha") ~= nil then

        request.abort()

    end

end
)

Recaptcha breaks Splash when using webkit engine. Take a look at this issue #1164
