Issue Description:

I have deployed a web service on Railway that runs both a backend (Node.js) and a Telegram bot concurrently. The service has been configured with environment variables in the Variables tab, specifically:

- GEMINI_API_KEY (for Gemini API)

- TELEGRAM_BOT_TOKEN (for Telegram Bot API)

However, when I check the service logs and application runtime, these environment variables are not being recognized by the application. The service tries to access these variables but returns undefined.

What I've verified:

- Variables are visible in the Railway dashboard Variables section

- The service is using a custom start script with concurrent execution

- The deployment shows as successful (ACTIVE status)

- GitHub repository is properly connected and recent commit was deployed

Error patterns:

- Application cannot initialize Gemini API client (missing API key)

- Telegram bot fails to connect (missing bot token)

Steps taken:

- Verified variables are set in the Variables tab

- Redeployed the service

- Checked the recent deployment logs

Could you help me troubleshoot why the environment variables are not being passed to the running service?
