I am creating a library within my current project. I am slowly moving components and services to that library in order to use the logic again in future apps. The problem I'm facing is the following :

src/app/core/interfaces/index.ts:1:15 - error TS6059: File 'C:/Users/Benjamin/Documents/Bizzpeek/coolabify/client/src/app/core/interfaces/AnyObject.ts' is not under 'rootDir' 'C:\Users\Benjamin\Documents\Bizzpeek\coolabify\client\projects\cloud-republic\src'. 'rootDir' is expected to contain all source files.        

1 export * from './AnyObject';

I don't really understand what is happening with this error, nor why it happens.
