Telegram web not loading properly

Unread post by unknownone » 2021-10-12, 15:23

Dear all,
I've tried today to open the Telegram web-based client https://web.telegram.org/k/ and it fails loading, while before it worked. I'm running Palemoon 29.4.1 x64 on Linux Ubuntu 20.04

The Error console provides this error message

Code: Select all

Error: ReferenceError: customElements is not defined
Source File: https://web.telegram.org/k/7.83a2dfdd0ee504f81f0b.chunk.js
The Developers tools console provides this:

Code: Select all

load state: timer started
27.d828877399fdc766a0f1.chunk.js:1
load state: 156ms
27.d828877399fdc766a0f1.chunk.js:1

ReferenceError: customElements is not defined[Learn More]

Is this an issue of my local browser configuration or does someone else experience the same issue?
Thank you

The answer is right there.. also you didn't bother to follow the instructions properly.
Better that a 100 probably guilty people die then one of them get a clean shot on me.

Sorry, I'm not sure to understand what I did wrong, except forgetting to use the code block which I fixed now.

Please try and include any relevant output from the Toolkit Error Console or the Developer Tools Web Console using the following procedure:

Clear any current output
Navigate or refresh the page in question
Copy and paste Errors or seemingly relevant Warnings into a single [ code ] block.
Name and domain of website reported, screen shot of webpage provided.
Output from Toolkit Error Console and the Developer Tools Web Console provided following exactly the procedure.

I see that the webpage loads a javascript and its processing fails at some point due to a ReferenceError, so the loading doesn't complete. Is this error a fault of my configuration?

No.
It's customElements (WebComponents), a Google/Chrome technology that Pale Moon does not yet support.

See: "custom elements" (UXP issues)

"customElements is undefined" (forum search)
"customElements is not defined" (forum search)
"WebComponents" (forum search)

Thank you all, I understand now the issue. Sorry that I didn't search the forum to check if the exact error message appeared on other websites. At least now other people will know that Telegram too is affected by this google mess.

The web is mostly an afterthought for these service providers and they will use Google technology to cater to 95% of the web browsers in use. I suggest using their desktop app and not a web browser. Telegram seems to be fairly light as far as chat clients go anyway unlike some others.
(Even though there is no objective reason to choose WebComponents for a chat interface, that is what they have done... Not really much we can do once that is done; appealing to them to undo Google WebComponents integration will likely not work as these companies in general see it as "part of a diverse and healthy set of modern web standards" which is literally what GitHub told me when bringing it up)

Thank you for the suggestion. I agree with your point of view ;) .
