Additional info

Also had same problem on a System with 23.0.3

[Aonodensetsu]

I have this problem since I installed, every version has it as far as my own copy goes; I've seen it mentioned years before but no solution that I have been able to find.

[SKB-CGN]

Same here!

[throny]

Additionally, this is something I saw when deploying the official docker image without modifications:

moment is deprecated: please ship your own, this will be removed in Nextcloud 20

Interesting then that it's still appearing in Hub 3 (NC 25).

[davkar3n]

same for me!

[nicokaiser]

At least the deprecation warnings should be removed. There are hundereds of them in the console, which not only makes Nextcloud look very unprofessional, but also they are simply wrong: "this will be removed in Nextcloud 20" did not happen, since the warning is still there in Nextcloud 25.

The deprecated modules should either really be removed (might possibly break a lot of things) or the warning should be removed.

[bhtooefr]

A workaround I've done on my install to make things not suck so hard:

Search for, in dist/core-main.js, the following function:

function(){void 0===window.TESTING&&console.warn.apply(console,arguments)}

Replace that function with this empty function:

function(){}

Performance is noticeably improved by not getting hundreds or thousands of jQuery deprecation warnings when using News.

Is that the right way to fix it? No. Is it effective? Seems so.

Hi, please update to 24.0.9 or better 25.0.3 and report back if it fixes the issue. Thank you!

My goal is to add a label like e.g. 25-feedback to this ticket of an up-to-date major Nextcloud version where the bug could be reproduced. However this is not going to work without your help. So thanks for all your effort!

If you don't manage to reproduce the issue in time and the issue gets closed but you can reproduce the issue afterwards, feel free to create a new bug report with up-to-date information by following this link: https://github.com/nextcloud/server/issues/new?assignees=&labels=bug%2C0.+Needs+triage&template=BUG_REPORT.yml&title=%5BBug%5D%3A+

[bhtooefr]

To be clear, my install had the issue on 25.0.3.

[szaimen]

Okay, thanks!

[SKB-CGN]

On my site also with 25.0.3 many JQuery Warning Logs.

[rickycraft]

Same problem with 25.0.3 using Docker nextcloud:latest on x64.

[pnurs]

Same here with NC 25.0.3 on 4 different installations.

[sergeng]

Same here with NC 25.0.3

[gonzalo]

same here with both NC 25.0.3 and 25.0.4

[assen-totin]

Yep! It's still here in NC 26. It is going to be before year 2099 when this will is fixed? Just curious.

[Aonodensetsu]

the milestone has been moved again to NC28 so i guess about that much time if not more

[nicokaiser]

The actual issue is "the deprecation warnings should be removed because nothing ever gets deprecated any time soon". Nextcloud development is focused on cramming new features into the old code base, instead of cleaning up and refactoring…

[bhtooefr]

Literally, I think it might be best to just implement my suggested workaround (the function is slightly different in 26) as a temporary thing, before things actually get fixed.

Nextcloud's front end, especially in News, is literally unusable due to the massive CPU load, even on reasonably fast platforms (Ryzen 7 5800X, Apple M2) on a Chromium-based browser (Vivaldi), because of the deprecation warning spam, unless I manually go in and make that function do nothing every single time there's a Nextcloud update (I'm using FreeBSD's package).

[kboykov]

CAN YOU ACTUALLY FIX THIS BUG? This problem is basically spamming the shit out of any browser's console. Just update the fking jquery version or remove the function that keeps on spamming these USELESS warnings.

[szaimen]

Done with https://github.com/nextcloud/server/pull/38852

[gonzalo]

@szaimen I don't really understand where the fix will be merged. Will be available for the 26 version of nextcloud server or just the 27?

[szaimen]

27.0.1

[gonzalo]

tks for the update. Will it be possible to have also in 26? We just moved to 26 and will keep there still for months
