Description

Gitea upgraded from 1.20.5 to 1.21.5, and the Web frontend gives an error:

JavaScript promise rejection: TypeError: Cannot read properties of undefined (reading 'facebook.json'). Open browser console to see more details.

The problem persisted even after Chrome's cache was cleared.

browser console output:

It is caused by your browser extension's bug.

If you don't like to see the message, you could add your customized CSS styles to hide such prompts (.js-global-error { display: none; }

@wxiaoguang Thanks, If it is a browser extension bug, try.gitea.io is fine.

Closing the browser extension DuckDuckGo can resolve this issue

Maybe we can somehow detect when a error is not coming from our scripts, and don't display errors from third-party scripts based on script file path.

Can someone link the extension that causes this from Chrome Store/Mozilla Addons?

Maybe we can somehow detect when a error is not coming from our scripts, and don't display errors from third-party scripts like extensions.

And maybe it's time to stop showing the JS errors to end users? Only show it in dev mode and for site admin?

That'd also be an option, but I'm not sure I like it too much because sometimes we do get valuable issue reports from it.

Can be reproduced with a Violentmonkey script:

// ==UserScript==
// @name        Gitea error trigger
// @match       http://localhost:3000/*
// ==/UserScript==
(async () => {
  throw new Error("error from userscript");
})()

So I checked it: It is possible in Firefox to detect extension scripts via error.stack?.includes('moz-extension://'), but that does not work in Chrome which shows nothing clearly identifyable. So yes I think we should go with @wxiaoguang's suggestion.
