Amplify Gen2 Sandbox复用已部署分支后端栈问题咨询

To make Amplify Sandbox use your existing deployed branch's backend stack (including seed data), follow these steps:

1. Generate configuration for your deployed branch
   Run the generate config command to create a configuration file pointing to your deployed stack. Replace YOUR_APP_ID and YOUR_DEPLOYED_BRANCH with your actual values:

   npx amplify generate config --app-id YOUR_APP_ID --branch YOUR_DEPLOYED_BRANCH --format json --out-dir config
   

   This creates amplifyconfiguration.json in the config directory, which contains the correct connection details for your deployed backend.

2. Launch Sandbox with the existing configuration
   Instead of using --config-out-dir (which generates a new config for a fresh temporary stack), use the --config flag to tell Sandbox to reuse your pre-generated config:

   npx amplify sandbox --config ./config/amplifyconfiguration.json
   

This connects Sandbox directly to your deployed backend, allowing you to use its resources and seed data for local development. Note that any local backend changes you make may prompt you to push updates to the deployed stack—be cautious if working with a production or shared environment.
