research the best ways to set convex env vars in a local deployment running in a sandbox. i want to read from a local .env file to inject the env vars but i get the problem of the backend not running when i set the env vars, so i try to start the dev server and it fails without the needed env vars

## Use Convex CLI or Dashboard for Dev Environment Variables In Convex, backend **environment variables** are managed per deployment. For a sandbox/dev deployment, the recommended approach is to use the Convex CLI or the Convex dashboard. You can set variables from your terminal with commands like: `npx convex env set YOUR_VAR "your-value"` ([docs.convex.dev](https://docs.convex.dev/production/environment-variables#:~:text=Environment%20variables%20can%20also%20be,modified%20with%20the%20comma...

# Configuring Environment Variables in Local Convex Deployments: A Comprehensive Guide This report explores the practical challenges and solutions for managing environment variables when running Convex in a local sandbox deployment. The core issue involves a circular dependency: local deployments require environment variables to function, yet accessing those variables requires the deployment to be running. This research examines multiple approaches to resolve this fundamental tension and establ...
