We could not create the data directory

[etornam45]

This is the error I had by running this code

const { Application } = require('@webviewjs/webview');

class WebView {
    constructor(options = {}) {
        this.app = new Application();
        this.window = this.app.createBrowserWindow();
        this.webview = null;
    }

    loadHTML(html) {
        this.webview = this.window.createWebview({
            html: html
        });
    }

    show() {
        this.app.run();
    }
}

module.exports = WebView;

I'm not so sure about the error, how are you executing the code? is it via sea or is it direct? @etornam45

Also, does this happen with bun/deno as well?

I don't know anything about "sea or direct" but I tried using bun and it worked, I haven't tried deno yes

I'm having the same issue. It seems related to this thread: https://stackoverflow.com/questions/66374105/opening-webview2-in-wpf-causes-system-unauthorizedaccessexception-while-calling

My specifics:

• Node v23.6.0
• webviewjs v0.1.3

my code:

import { Application } from '@webviewjs/webview';

const app = new Application();
const window = app.createBrowserWindow();
const webview = window.createWebview();

webview.loadUrl('https://nodejs.org');

app.run();

Error log:

const webview = window.createWebview();
                       ^

Workaround: Set the environment variable WEBVIEW2_USER_DATA_FOLDER to a writeable location.

import { Application } from '@webviewjs/webview';

process.env.WEBVIEW2_USER_DATA_FOLDER = process.cwd();

const app = new Application();
const window = app.createBrowserWindow();
const webview = window.createWebview();

webview.loadUrl('https://nodejs.org');

app.run();
