Environment variables specified on app.yaml but it's not fetching on main.go <p>I've specified my environment variables in app.yaml and it's being fetched when I'm running it on my local machine but once I have it deployed - it's not fetching it. </p> <p>Here's how I've set it up:</p> <pre><code>application: some-application version: 1 runtime: go api_version: go1 threadsafe: true handlers: - url: /.* script: main.go secure: always env_variables: ENVIRONMENT_VAR1: 'some key' ENVIRONMENT_VAR2: 'some key' ENVIRONMENT_VAR3: 'some key' </code></pre> <p>And I'm using <code>os.Getenv("ENVIRONMENT_VAR1")</code> to retrieve the key and it works when I run it on my local but fails to work when deployed on google app engine. </p>
