Moving an app to codesandbox

I got one of my apps working in my local environment following the tutorials and then I decided to see if I could port it to codesandbox. I followed the pattern I saw in:

When I run it, I get:

ModuleNotFoundError
Could not find module in path: ‘cldrjs’ relative to ‘/node_modules/globalize/dist/globalize/message.js’

and the stacktrace shows it to be from widgets/toolbar:

import Toolbar from ‘@dojo/widgets/toolbar’; in Menu.ts
