Hey there! The

sandboxId

is usually set up in the

.env

file of your project. Once you’ve installed the Next.js code and started with

pnpm dev

, here’s a simple way to find or set it up: 1. Take a look at the

.env

file in the root of your project. You should see a line like

SANDBOX_ID=

. If it’s not there, don’t worry—check if there’s a

.env.example

file you can use as a guide. 2. Go ahead and set the

SANDBOX_ID

to your actual sandbox identifier from your LiveKit Cloud dashboard. 3. After you make these changes, be sure to restart your development server so it picks up the new environment variables. If you run into any errors while running your app, like a missing or incorrect

sandboxId

, just double-check your configuration and make sure the

.env

file is properly set up. And of course, if you need any more help, feel free to reach out—I’m here for you! Sources: .env.example | complex-agents/nova-sonic/nova-sonic-form-agent/.env.example | .env.example | .env.example | swift-frontend/VisionDemo/.env.example.xcconfig
