I am currently developing a React Native application using AWS Amplify and Expo, and I’ve run into a persistent issue after updating the Expo SDK from version 40 to 50. The following TypeError is thrown when I attempt to run the application:

TypeError: /codebuild/output/src3477756040/src/ennma_app/node_modules/expo-router/_ctx.web.js: Expected `fromDir` to be of type `string`, got `undefined`

enter image description here

Environment

• AWS Amplify
• React Native
• Expo SDK 50

Relevant package.json entries:

{
  "dependencies": {
    "expo": "~51.0.0",
    "expo-router": "~3.5.10",
    ...
  }
}

I have already tried the following info without success

expo sdk 40 metro.config.js “Expected ‘fromDir’ to be ‘string’, got ‘undefined’ ”
https://github.com/kristerkari/react-native-svg-transformer/issues/329

The error persists, and it seems to be related to how expo-router handles directory paths post-SDK update. Has anyone encountered a similar issue, or does anyone have insights on how to resolve this fromDir TypeError?
