Reloading expo app throws Error: Failed to create a new MMKV instance: react-native-mmkv 3.x.x requires TurboModules
I’m encountering this error when reloading an Expo Prebuild React Native 20.0.2 app that uses [email protected]. Even though the New Architecture is explicitly enabled in my project, MMKV initialization fails at runtime, specifically on app reload.
app.config.json
`` import type { ConfigContext, ExpoConfig } from '@expo/config'; import type { AppIconBadgeConfig } from 'app-icon-badge/types';
import { ClientEnv, Env } from './env';
const appIconBadgeConfig: AppIconBadgeConfig = { enabled: Env.APP_ENV !== 'production', badges: [ { text: Env.APP_ENV, type: 'banner', color: 'white', }, { text: Env.VERSION.toString(), type: 'ribbon', color: 'white', }, ], };
