Mostly empty page on most page loads

[jrfnl]

As of today, I'm seeing mostly empty pages on initial page load:

This is accompanied by the following JS error:

12:32:57.307 TypeError: parent is null

Doing a reload/F5 allows for the page to display, but having to do that every other click gets old fast.

I can replicate on recent (UXP-based) Serpent 52.9.0; it's quite random, though, but, as OP mentioned, quite annoying 😞 ...

It does happen also with latest palefill, which was recommended as a substitute for this, no longer maintained, extension...

Since the TypeError message is generated from the following GH script:

https://github.githubassets.com/assets/chunk-vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-539e3d6a1773.js

... I tried blocking it with uBlock Origin (legacy),

"My Filters" tab, add:

! github.com
||github.githubassets.com/assets/chunk-vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-539e3d6a1773.js$script,important

... and I haven't witnessed any breakage thus far... YMMV, of course 😉 .
This isn't a solution per se, just a "dirty" workaround...

[Vangelis66]

... Today, GH have started serving another manuelpuyol_turbo script that breaks things for me (latest Serpent 52.9.0 32-bit),

https://github.githubassets.com/assets/vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-b12e520649c0.js

I've blocked that one too in uBlock Origin (legacy), so far so good:

! github.com
||github.githubassets.com/assets/chunk-vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-be659c79aff6.js$script,domain=github.com,important
||github.githubassets.com/assets/vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-b12e520649c0.js$script,domain=github.com,important

01/07/2022 EDIT:
It looks like that second script is no more being served:

https://github.githubassets.com/assets/vendors-node_modules_manuelpuyol_turbo_dist_turbo_es2017-esm_js-b12e520649c0.js => Not Found 

so the blocking rule initially posted in my previous comment should be just enough for now... 😉

Looks like the Palefill extension doesn't solve this issue so far and I don't have the uBlock origin extension.

might make sense to contact that dude and tell him to fix his shit

Looks like they flicked a switch that enables (eg, environment-e9a18cc2906a.js:1:1909) v=n(y=>y?.tagName==="TURBO-FRAME", ...) instead of v=n(y=>(y?y.tagName:null)==="TURBO-FRAME", ...) or v=n(y=>(y && y.tagName)==="TURBO-FRAME").

might make sense to contact that dude and tell him to fix his s**t

... Well, he's on GitHub,

https://github.com/manuelpuyol

currently "Building UI @github" and committing code to
https://github.com/github/browser-support
(among others...)

@dirkf
Is your log from SeaMonkey 2.53?
Looks like they broke browsers without native Optional Chaining Operator ("?.") support 😠 ...

Addendum: In a Chromium 78 fork (360EEv12), at least one of the GH scripts now also requires native browser support for the Nullish Coalescing Operator ("??"):

Uncaught SyntaxError: Unexpected token '?'  https://github.githubassets.com/assets/vendors-node_modules_lit-html_lit-html_js-50b1c3ae31f7.js:49

[dirkf]

2.53.12.
Forthcoming 2.53.13 has ?. but may break other extensions in interesting ways.

ok, i'll use my magical powers to summon him @manuelpuyol @manuelpuyol @manuelpuyol

Unfortunately it's not Manuel's source that's the problem, it's how GH sends the code, as well as their apparent complete lack of anything that might pass for version control or release management, which is really beyond ironic.

[roytam1]

a test version with following commits from palefill included:
martok/palefill@1526928 (with fix in comment applied)
martok/palefill@7f939eb
martok/palefill@c3b6679

(rename to .xpi to install)
github-wc-polyfill-1.2.19.1-unofficial.zip

(EDIT: updated version in #68 (comment) )

[AroKol78]

github-wc-polyfill-1.2.19.1-unofficial

generally solves the problem.
sometimes "discussions" are displayed strangely (it helps to reload the page)

Just updated to latest Palemoon (v31.1.0) so just I could use this shit site again and vangelis66 uBlock directive made it finally usable. Thanks dude!

And while at it, holy shit, it's all getting to the point of no return faster and faster. Meanwhile, child of the moon can't commit a single C++ line of code to address any of these major websites breakages.

It was all a scam from the beggining. At this pace, SerenityOS libweb will be more compliant with shitty modern webtech standards faster then one can write "lol, just use Chrome dude".
