Cannot read property 'transformFile' of undefined

[RohithPalagiri-BO]

What is the current behavior? I am running into this issue when attempting to build my iOS app in a Release scheme either via Xcode or via the expo CLI. I am able to successfully run the app in the simulator in debug mode.

With the expo-cli the command is npx expo run:ios --configuration Release

Please provide your exact Metro configuration and mention your Metro, node, yarn/npm version and operating system.

React Native v0.73.4 Node v18.17 Expo v50 (Bare Workflow)

This is the default generated config

// Learn more https://docs.expo.io/guides/customizing-metro
const { getDefaultConfig } = require('expo/metro-config');

/** @type {import('expo/metro-config').MetroConfig} */
const config = getDefaultConfig(__dirname);

module.exports = config;

Things I've tried:

• Deleting package-lock.json, node modules, pods, podfile.lock and reinstalling all of them
• Deleting and rebuilding iOS build folder
• Attempted to downgrade to lowest Node version (v18)
• export NODE_OPTIONS=--openssl-legacy-provider in terminal
• npx expo install --fix this was a fresh project so there wasn't anything
• npx react-native start --reset-cache

Facing the same issue. I have tried with node 14, 16, 17, 18 and 20 without any luck..
