Description of the bug

'EAS build' fails when run via github action.
'EAS build' succeeds when run via local terminal.

To Reproduce

What steps did you perform which led to this issue?

1. Set up GitHub Action with this yml, which I've named 'eas-build-on-push.yml':

name: EAS Build on Push to Main

on:
  push:

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: 🏗 Setup repo
        uses: actions/checkout@v3
        
      - name: Log working directory after checkout
        run: pwd

      - name: 🏗 Setup Node
        uses: actions/setup-node@v3
        with:
          node-version: '20'
          cache: 'npm'
          cache-dependency-path: client/package-lock.json

      - name: Log working directory after setup Node
        run: pwd

      - name: 🏗 Setup EAS
        uses: expo/expo-github-action@v8
        with:
          eas-version: latest
          token: ${{ secrets.EXPO_TOKEN }}

      - name: 📦 Install dependencies
        run: npm install
        working-directory: client

      - name: Log working directory after install dependencies
        run: pwd
        working-directory: client

      - name: 🚀 Build app
        run: eas build -p android -e test
        working-directory: client

      - name: Log working directory after build
        run: pwd
        working-directory: client

2. Push from my local computer
3. EAS build starts
4. EAS build fails. Here is an extract of the output from expo.dev builds:
   

Expected behavior

EAS build is successful.
If I execute eas build from my local terminal on the same commit, the build is successful.

Actual behavior

Build is not successful.

Additional context

I suspect the issue may relate to my folder structure.

Relevant folders from my root are:
.github/workflows
.git/
/client/
/server/

Package-lock.json is here:
/client/package-lock.json
