Reproduction steps

Created a monorepo with Turborepo.

The apps/mobile-app folder contains an Expo mobile app.

The packages/backend folder contains the Amplify backend.

After trying to run npx ampx sandbox, I see the error output above.

I may have "solved" this issue. I ended up:

• Ran npx ampx sandbox delete
• Updated to Node 21.6.2
• Removed yarn.lock and node_modules
• Ran yarn install

Then my sandbox command appears to be working.

Hey @chrisl777, glad to hear updating the NodeJS and re-installing the dependencies fixed the issue. But wanted to get a quick confirmation on the dependencies the error was occurring on. Were the dependencies installed in the root package.json or the under the amplify folder?
