Most likely your application or website requires environment variables to function properly.
Most NodeJS based apps for example require a NODE_ENV variable. Forest.host also provides a set of system variables that can be used in your application, like database credentials.
Add any environment variables you require.
Also copy any variable names you might need in your app’s configuration.
We have more documentation about environment variables available in our documentation section here.
Note that environment variables will be available after a deploy. If you’re service is already running, either use redeploy or trigger a new build. If you are following this guide step by step, this wont be an issue right now.
