Upgrade Expo CLI have unknown error --assetPlugins
I upgrade to latest Expo CLI 2.19.2 and tried upgrade my expo application using SDK 33.
When I called expo start, i have a message saying:
Opening DevTools in the browser... (press shift-d to disable) error: unknown option `--assetPlugins'
Metro Bundler process exited with code 1 Set EXPO_DEBUG=true in your env to view the stack trace.
I tried to set EXPO_DEBUG=true on Mac but doesn't show any debugging details when running expo start again.
I found it i should called export EXPO_DEBUG=true
Here is additional message:
error: unknown option `--assetPlugins'
Metro Bundler process exited with code 1 Error: Metro Bundler process exited with code 1 at ChildProcess.

Be sure to also upgrade "react-native" to version 33.
yarn add react-native@https://github.com/expo/react-native/archive/sdk-33.0.0.tar.gz
Also check "jest-expo" has been updated and you change the "sdkVersion" in app.json to match SDK 33.
