The string did not match the expected pattern in evaluateJavaScript

I've loaded a page and am looking for all the <script> with type=text/javascript, but no matter what I do I get an exception

webView.evaluateJavaScript("document.querySelectorAll('script[type=text\\/javascript]').length;)

The string did not match the expected pattern.

webView.evaluateJavaScript("document.querySelectorAll('script[type=text/javascript]').length;)

The string did not match the expected pattern.

webView.evaluateJavaScript("document.querySelectorAll('script').length;)

Got no clue how to add a type filter in there, it works in the Console in Safari

It works for me

    func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
    webView.evaluateJavaScript("document.querySelectorAll('script[type=\"text/javascript\"]').length;") { result, err in
        print(result ?? "")
        print(err ?? "")
    }

}
