I just updated to this : Commits · discourse/discourse · GitHub 2f398db9b66f19220b5a7f56721a68f41dcdeeec
Two different theme components now completely break my site. They are the “Modern Category + Group Boxes” from Air Theme and Avatar Size and Shape
They render the site unusable (looping?). Happens on both Firefox and Chrome (desktop)
I have tried them with no plugins and in isolation on different themes (ie safe mode with no plugins and on an isolated theme), so I don’t think it’s specific to my instance.
Console reports lines like this:
Uncaught TypeError: Cannot read properties of null (reading ‘syscall’)
Uncaught (in promise) TypeError: Invalid value used as weak map key
message-bus.js:118 MESSAGE BUS FAIL: callback /latest caused exception TypeError: Cannot read properties of null (reading ‘syscall’)
As a temporary solution, I have forced my users onto a generic theme until it’s figured out. Please let me know if you can replicate this error.

I’m experiencing the same issue on my site. For example, when I log out, the page turns completely white with the same error. Some users also reported that they can’t log in because the page is just blank. It seems to happen randomly.
The main problem is that there’s no clear error message to indicate what’s causing it. I tried to track it down by checking my theme components. I’ve already updated most of them to gjs, but here’s the interesting part: when I deactivate and then reactivate a specific component, the site starts working again without errors. I still don’t know what’s causing this issue though… It seems that the problem only occurs on pages where a (custom) theme component is present. So at least this gives me a clue that the issue must be coming from one of the components.

This might help track it down:
Thank you. This really helps with the developer experience.
Which as we know has improved dramatically with.gjs over widgets.
however
There are lots of very odd errors you can get when using gjs components that do not make finding the issues very easy.
For example, lets mess up the helper name:
{{html_safe this.bannerTextContent}}
Leads to the classic:
program.js:100 Uncaught (in promise) TypeError: Invalid value used as weak map key at WeakMap.set (<anonymous>)
(this also happens…
Check the helpers!

Here is a simple theme I set up that only has the avatar component: Elite Fourum - E4 - efour
https://www.elitefourum.com/latest?safe_mode=no_plugins&preview_theme_id=39
I can repo the issue at this link on firefox and chrome (desktop)
Modern Category + Group Boxes : Elite Fourum - E4 - efour
https://www.elitefourum.com/?safe_mode=no_plugins&preview_theme_id=58
this one seems harder to repo. It causes issues when I’m logged into my admin account (chrome and firefox) but not when I try on a dummy account. The bugs seem similar though between both theme component so maybe fixing one will solve the other.
Hope it helps!

the closest thing I could get to an iterpretable error message is
client-error-handler.js:125 [THEME 39 ‘Test’] Error: Could not find module admin/components/color-input imported from (require)
the customize-edit-category-general.js is coming from the Air Theme:
import { cancel } from "@ember/runloop";
import { withPluginApi } from "discourse/lib/plugin-api";
export default {
name: "customize-edit-category-general",
initialize() {
withPluginApi("0.8.14", (api) => {
api.modifyClass("component:edit-category-general", {
pluginId: "discourse-air",
didInsertElement() {
this._super(...arguments);
document.body.classList.add("edit-category");
this._focusCategoryName();
in core:
import categoryBadge from "discourse/helpers/category-badge";
import { categoryBadgeHTML } from "discourse/helpers/category-link";
import lazyHash from "discourse/helpers/lazy-hash";
import {
CATEGORY_STYLE_TYPES,

This looks like the same issue: Forum navbar is repeating

This will fix the color-input error from the air theme. But this issue is not new, so I think it’s unlikely to be the cause of these rendering errors
main ← optional-require-color-input
opened 06:13PM - 02 Sep 25 UTC
This import will fail for non-admin users. Most of the time this isn't causing a… problem, since `edit-category-general` isn't imported by non-admin logic. However, if a theme imports or calls `modifyClass` on it, this import will be evaluated and fail.
This was affecting an initializer in the discourse-air theme for non-admin users. However, the automatic error recovery for theme initializers caught it, so the only impact was a console log.

@piffy האם תוכל בבקשה לנסות לעדכן לגרסה העדכנית ביותר של tests-passed, למקרה שתיקון ה-color-input יעזור בכל דרך שהיא.
בהנחה שהדברים עדיין שבורים לאחר בנייה מחדש, האם תוכל לנסות זאת:
./launcher enter app
rails c
Discourse.clear_all_theme_cache!
אותו הדבר לגביך @don , אם יש לך זמן.
אם זה פותר את הבעיה, אז זה מצביע על כך שיש לנו בעיה עם ביטול תוקף מטמון הנושא (theme cache invalidation) שאמור היה לקרות כאשר העלנו את גרסת Ember בשבוע שעבר.

אוקיי נהדר, תודה על האישור! ננסה לפתור את הבעיה הזו במערכת המטמון של הנושאים, כך שלא יידרש פעולה ידנית.
אבל בינתיים, לכל מי שנתקל בבעיות אלו:
Uncaught TypeError: Cannot read properties of null (reading ‘syscall’)
Uncaught (in promise) TypeError: Invalid value used as weak map key
אנא בצע את הצעדים הבאים בקונסול:
./launcher enter app
rails c
Discourse.clear_all_theme_cache!

I haven’t been able to reproduce the problem, but I did find one possible problem which is specific to the way UI-based upgrades work. This should take care of it:
main ← ember-version-cache
opened 08:59PM - 02 Sep 25 UTC
During in-container updates, the old version of the application continues runnin… g while an update is applied. That means that it's possible for the `node_modules/ember-source` version to be different to the version currently loaded in the transpiler. That means it's theoretically possible for theme assets to be built with the old compiler, and then stored against the new version.
This commit removes that race condition by adding an `ember_version` method to the JS transpiler. This is guaranteed to give us an accurate version number for the template-compiler currently being used for themes.
This commit also bumps the BASE_COMPILER_VERSION to force a recompile on any sites affected by this race condition.
It also forces a recompilation, so sites that have already been affected by this bug will be sorted after their next update.
