Use Deep Link, occur error

I'm using Deep link refer to doc: https://reactnavigation.org/docs/deep-linking#setup-with-expo-projects.

• Install dependencies:

{
  "dependencies": {
       "expo": "^49.0.13",
       "expo-linking": "~5.0.2"
   }
}

• Configure my app.json

{
  "name": "ReactNativeDemo",
  "displayName": "ReactNativeDemo",
  "expo": {
    "scheme": "mychat"
  }
}

• import and use Deep Link

import * as Linking from 'expo-linking'

// the following code caused an error to occur
const prefix = Linking.createURL('/')

function App() {
  const linking = {
    prefixes: [prefix]
  }

  return (
    <NavigationContainer linking={linking} fallback={<Text>Loading...</Text>}>
      {/* content */}
    </NavigationContainer>
  )
}

• error message in my ternimal, but compiler is successfull, error occur only running app in ios simulator

Error: expo-linking needs access to the expo-constants manifest (app.json or app.config.js) to determine what URI scheme to use. Setup the manifest and rebuild: https://github.com/expo/expo/blob/main/packages/expo-constants/README.md, js engine: hermes

How should I solve this error???

Start with the deep-linking documentation linked in the report and compare its Expo setup with the shown app.json, expo-linking, and NavigationContainer usage. Reproduce the error in an iOS simulator using the provided example, then determine whether the documentation needs clarification about the manifest and rebuild requirements. Done means the documented setup addresses this runtime error or clearly explains the required configuration.
