I’m trying to set up environment variables in a GitHub Actions workflow for my React Native Android build (./gradlew bundleRelease). Despite setting the environment variables either through the env section or using export commands, the build is not recognizing some of the variables. Specifically, I keep getting errors stating that certain environment variables are missing during the build process.

Here are the methods I’ve tried:

1. Setting the environment variables directly using GitHub Actions’ env syntax:

   - name: Set environment variables
     env:
       MAIN_URL: ${{ vars.MAIN_URL }}
       ORIGIN: ${{ vars.ORIGIN }}
       ENV: ${{ vars.ENV }}
       AWS_REGION: ${{ secrets.AWS_REGION }}
       AWS_USER_POOL_ID: ${{ secrets.AWS_USER_POOL_ID }}
       AWS_APP_CLIENT_WEB_ID: ${{ secrets.AWS_APP_CLIENT_WEB_ID }}
       AWS_IDENTITY_POOL_ID: ${{ secrets.AWS_IDENTITY_POOL_ID }}
       AWS_EXTERNAL_USER_POOLS_ID: ${{ secrets.AWS_EXTERNAL_USER_POOLS_ID }}
       AWS_EXTERNAL_USER_POOLS_WEB_CLIENT_ID: ${{ secrets.AWS_EXTERNAL_USER_POOLS_WEB_CLIENT_ID }}
       ENABLE_SENTRY: ${{ secrets.ENABLE_SENTRY }}
   

2. Exporting the environment variables using export:

   - name: Export environment variables
     run: |
       export MAIN_URL=$MAIN_URL
       export ORIGIN=$ORIGIN
       export ENV=$ENV
       export AWS_REGION=$AWS_REGION
       export AWS_USER_POOL_ID=$AWS_USER_POOL_ID
       export AWS_APP_CLIENT_WEB_ID=$AWS_APP_CLIENT_WEB_ID
       export AWS_IDENTITY_POOL_ID=$AWS_IDENTITY_POOL_ID
       export AWS_EXTERNAL_USER_POOLS_ID=$AWS_EXTERNAL_USER_POOLS_ID
       export AWS_EXTERNAL_USER_POOLS_WEB_CLIENT_ID=$AWS_EXTERNAL_USER_POOLS_WEB_CLIENT_ID
       export ENABLE_SENTRY=$ENABLE_SENTRY
   

Configure project :app
Reading env from: .env

*** Missing .env file ****

However, the build command (./gradlew bundleRelease) does not seem to recognize the variables and throws errors about missing values. What am I doing wrong?
