Current behavior

When executing npm run build:prod in the starter or showcase we get errors about "cacheGroups" (does not exist in the schema).

Also those warnings:

Regarding the issue about the linting warnings, for example: Warning: The 'no-array-delete' rule requires type information, I have created this issue #405 to track it.
