Describe the Bug

Local dev server stops with an error: Error: Cannot find module 'scheduler/package.json'.

I assume this comes in relation with the recent changes in this line in webocket-config.js.

I believe we scheduler must be removed from topLevelFrameworkPaths to make it work correctly.

Complete error:

I have the same issue. My workaround until this is fixed is installing scheduler with npm install scheduler.
