Web Inspector crashes on `style.ownerStyleSheet.isInspectorStyleSheet`

paco · Dec 2, 2022

Steps to reproduce:

Visit https://docs.family.co/connectkit/auth-with-nextjs#siwe-nextjs-implementation-1-install
Open the web inspector and try to inspect a few DOM elements
The Web Inspector crashes with the following error:

TypeError: null is not an object (evaluating 'style.ownerStyleSheet.isInspectorStyleSheet') (at StyleOriginView.js:52:42)
    update @ StyleOriginView.js:52:42
    layout @ SpreadsheetCSSStyleDeclarationSection.js:192:37
    _layoutSubtree @ View.js:304:20
    _layoutSubtree @ View.js:315:32
    _layoutSubtree @ View.js:315:32
    _layoutSubtree @ View.js:315:32
    _visitViewTreeForLayout @ View.js:383:36

This issue also occurs when compatibility mode is ON.

Expected behavior:

The web inspector should not crash.

paco not able to reproduce. Did you try compatibility mode?

Steps to reproduce:

Open Web Inspector and select an element in the DOM tree
Edit a CSS rule

Expected behavior:
The rule should update as usual, but sometimes the Web Inspector crashes and I can't think of any reason it does vs the times it updates correctly.

Here's the exception stack trace:

I experiencing it yesterday too. I just reopen the inspect element. Not identical, but it's crashing, because I forgot to screenshot, I forgot the detail, but it's great to widely test this feature tho.

ImBIOS Yeah there seems to be a few situations where the Web Inspector crashes; I'm trying to document them when I can reproduce them but sometimes they're a bit hard to make happen reliably, so if yours crashes and you get a different stack trace at the bottom of the crash screen I'm sure the devs would appreciate you pasting that here!
