The root cause is almost always the same: you didn't have the right configuration variables set up. This is where the .env.sample file—also commonly named .env.example —becomes indispensable. This humble template file is the bridge between a working codebase and a developer's local environment, serving as documentation, a safety net, and a contract all in one.
