Overall the plugin works great, but from time to time I'm receiving the following error.

I opened a ticket on JCEF about sourcemap not available in DevTools, see https://bitbucket.org/chromiumembedded/java-cef/issues/403/devtools-cannot-load-sourcemap-files-net

I have Java code that expose a progressive web app via JCEF. However the third-party web-app javascript is minified. They do provide source maps however. This works fine in a usual browser.

However when running inside a JCEF frame, the devtools cannot load these source maps.

DevTools failed to load SourceMap: Could not load content for https://my-app/2.c9d7d260.chunk.js.map: Connection error: net::ERR_NAME_NOT_RESOLVED
DevTools failed to load SourceMap: Could not load content for https://my-app/main.a7bce6af.chunk.js.map: Connection error: net::ERR_NAME_NOT_RESOLVED
DevTools failed to load SourceMap: Could not load content for https://my-app/main.0d980f3a.chunk.css.map: Connection error: net::ERR_NAME_NOT_RESOLVED

I am registering a custom scheme handler

CefApp.getInstance().registerSchemeHandlerFactory(
    "https", appDomain,
    SchemeHandlerFactory { uri: URI ->
        BufferedInputStream(WebView::class.java.getResourceAsStream("/assets" + uri.path))
    }
).also { successful -> assert(successful) }

I even tried to hook a request handler

object : CefRequestHandlerAdapter() {
    override fun getResourceRequestHandler(
        browser: CefBrowser?,
        frame: CefFrame?,
        request: CefRequest?,
        isNavigation: Boolean,
        isDownload: Boolean,
        requestInitiator: String?,
        disableDefaultHandling: BoolRef?
    ): CefResourceRequestHandler? {
        println(request)
        return super.getResourceRequestHandler(
            browser,
            frame,
            request,
            isNavigation,
            isDownload,
            requestInitiator,
            disableDefaultHandling
        )
    }
}.also { requestHandler ->
    cefBrowser.client.addRequestHandler(requestHandler)
    lifetime.onTermination {
        cefBrowser.client.removeRequestHandler()
    }
}

Debugging at these location didn’t help much, as I don’t see any request to https://my-app/2.c9d7d260.chunk.js.map for example.

I am not sure if this is a bug or a missing feature, or simply a misuse.

I even tried to add this request handler on the devtool browser cefBrowser.devTools

Here is a proposed solution for issue #91. The idea is for the scratch menu(s) to default to the Excalidraw UI instead of JSON editor when creating new file.

It doesn't appear that the current plugin supports toggling light mode independent of the IDE color scheme. Would it be possible to add this in a future release?

When saving drawing into PNG or SVG, nothing happens. In logs, I'm receiving an error:

Currently, the default file type for Excalidraw on the scratch menu is a JSON type, which causes the IDE to open a new JSON editor instead of a diagram editor. As an enhancement, it would be nice if the scratch file menu instead opened a diagram editor so users could go straight to the Excalidraw UI.
