Edit the Appfiles to ensure they have adequate metadata for your app.
    
      
 Check that package_name in
 [project]/android/fastlane/Appfile matches your package name in AndroidManifest.xml.
      
 Check that app_identifier in
 [project]/ios/fastlane/Appfile also matches Info.plist’s bundle identifier. Fill in
 apple_id, itc_team_id, team_id with your respective account info.

Set up your local login credentials for the stores.
    
      
 Follow the Supply setup steps
 and ensure that fastlane supply init successfully syncs data from your
 Play Store console. Treat the .json file like your password and do not check
 it into any public source control repositories.

      
 Your iTunes Connect username is already
 in your Appfile’s apple_id field. Set the FASTLANE_PASSWORD shell
 environment variable with your iTunes Connect password. Otherwise, you’ll be
 prompted when uploading to iTunes/TestFlight.
