Encountered undefined provider error after importing CacheService

[Srinivasalapati]

Dear Team,

I see that the issue after installing importing and keep provider as CacheService in component.
Uncaught Error: Encountered undefined provider! Usually this means you have a circular dependencies (might be caused by using 'barrel' index.ts files.

Below is the error, can you please help with it?
