1876696 - Debugger "watch expression" of jQuery expression might cause DOMException, evaluation in console works though

Status: RESOLVED DUPLICATE of bug 1876297

(DevTools :: Debugger, defect, P2)

Description

[thecodemonkey86]

Attachment: bugzilla_screenshots.zip

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:122.0) Gecko/20100101 Firefox/122.0

Steps to reproduce:

I added javascript (jQuery) expression of custom script to watched expressions (don't know if that's the correct name in English localization) in debugger. In my case that expression was $(item).data("fontSizeCaption"), script looks something like this

// ... more code here ...
function getStampsJson(pageId) {
let arrStamps = [];
items.each(function (index,item){
let tplId = $(item).data("templateId");
let fontSizeCaption = $(item).data("fontSizeCaption");
// ... more code here ...
});
// ... more code here ...
return arrStamps;
}
// ... more code here ...

Actual results:

In watched expressions the debugger reports a DOMException, evaluation in console of the exact same expression prints the correct value though

Expected results:

correct value in debugger as well, same value as printed in console

I think the issue was fixed in Firefox 124 Bug 1876297 .
At least if I go on https://jquery.com/ , and add a watch expression like $("ul.projects > li").html(), I don't get an error (but the same value as I'm getting from the console evaluation).

Are you seeing this issue yourself? If so, can you check your Firefox version, and if it's 124 or more, can you share a URL/projects with steps to reproduce the issue?

Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE.
