The application I'm currently working on uses WebKit. Based on the crash analytics, we have noticed that some of our users are experiencing an unusual behavior in the app's WebKit view with macOS 15.3.2. These errors are reported for this version of the OS. The error in the crash log is a SIGABRT error, but there is no relevant information available to address it. In some crash logs, we found this error: "NSInternalInconsistencyException: Returned WKWebView was not created with the given configuration" but there is not any particular way to address it. Is there a way to identify the cause of this error? Alternatively, has anyone encountered this issue and found a solution?

You can see the code that throws this error in the WebKit open source. Actually, it can come from a few places. The first one is here, and the remaining ones are shortly after that.

Here’s roughly what it means:

The web view has called your webView(_:createWebViewWith:for:windowFeatures:) delegate method, passing it a configuration (WKWebViewConfiguration) to use.
That’s return a new web view instance (WKWebView).
That instance wasn’t created from the configuration supplied in step 1.

The docs for that delegate method say:

The web view returned must be created with the specified configuration.

and WebKit throws this exception if you don’t meet that requirement.

Hey, Eskimo!

Thank you for the reply.

There were also some crashes where the backtrace was the same as this one, but in the info, they addressed the abort(). I'm not sure if that also occurs due to configuration or not.

Moreover, as per your comment. I can check that where we should pass the configuration while opening the new window that has the same configuration as its parent webview has.

My question is, can we alter the configuration of the new webview on webView(_:createWebViewWith:for:windowFeatures:) delegate call?

 override func webView(_ webView: WKWebView, createWebViewWith configuration: WKWebViewConfiguration, for navigationAction: WKNavigationAction, windowFeatures: WKWindowFeatures) -> WKWebView? {
      
            let popupWebView = WKWebView(frame: self.view.bounds, configuration: configuration)
            popupWebView.customUserAgent = webView.customUserAgent
            popupWebView.navigationDelegate = self
            popupWebView.uiDelegate = self
            popupWebView.frame = self.bounds
            popupWebView.autoresizingMask = [.width, .height]
            if let subView = popupWebView {
                self.view.addSubview(subView)
            }
            self.view.autoresizesSubviews = false
            
            popupWebView.configuration.preferences.javaScriptCanOpenWindowsAutomatically = true
            popupWebView.configuration.preferences.javaScriptEnabled = true
            popupWebView.configuration.preferences.plugInsEnabled = true
            popupWebView.load(navigationAction.request)
 
            return popupWebView
    }

can we alter the configuration … ?

Hmmm, there’s three levels to that:

Can you actually do it? — Sure. WKWebViewConfiguration has a bunch of read/write properties and you can change them before create your web view.
Will it trap? — I don’t think so, but you’re in a better position to answer that than me. Just suck it and see.
Is it a valid use of the API? — I don’t have an answer to that. It’s a WebKit policy question and WebKit isn’t really my specialty.
