## Problem 2FA is broken on prod (critical, reported on Discord and in #21649): instead of the 2FA setup screen, users hit the app-wide error page — both at login-time provisioning and on **Settings > Profile > Two-Factor Authentication**. The 2FA screen flashes briefly (loader) and then the error page replaces it. Fixes #21649. ## Root cause The crash is a React render error — *"Element type is invalid: got object"* — at the exact moment the QR code renders (when `qrCode` flips from `null` to a value). `react-qr-code` is a CommonJS package (`__esModule: true`, `exports.default = QRCode`). The recent **Vite 8 / rolldown** bundler migration changed how its CommonJS default export is resolved into an ESM import: `import QRCode from 'react-qr-code'` now resolves to the **module namespace object** `{ default, QRCode }` instead of the component itself. Rendering that object as a React element throws and trips the error boundary. The import code never changed — only the bundler's module resolution did, which is why this regressed without any 2FA code change. Reproduced the resolution with an esbuild/rolldown-style bundle: the default import comes back as `{ default, QRCode }`, with the real `forwardRef` component sitting on `.default`. ## Fix Add a small `resolveCjsModuleDefaultExport` helper that returns the default export when a CommonJS import is handed back as a namespace object, and a no-op otherwise. Use it in the two 2FA QR render paths: - `SignInUpTwoFactorAuthenticationProvision.tsx` (login-time provisioning) - `SettingsTwoFactorAuthenticationMethod.tsx` (profile settings) ## Verification - `npx nx lint:diff-with-main twenty-front` ✅ (lint + format) - `npx nx typecheck twenty-front` ✅ (CI)

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
