Error from SlideComponent when packaging using ng-packagr

Hi guys, when I try to package up my module using ng-packagr, I get the following error from the compiler:

Start your code here

BUILD ERROR (1,1): : Directive ɵd1, Expected 0 arguments, but got 1. (1,1): : Directive ɵe1, Property 'carousel' is protected and only accessible within class 'SlideComponent' and its subclasses. (1,1): : Directive CarouselComponent, Expected 0 arguments, but got 1. Error: (1,1): : Directive ɵd1, Expected 0 arguments, but got 1. (1,1): : Directive ɵe1, Property 'carousel' is protected and only accessible within class 'SlideComponent' and its subclasses. (1,1): : Directive CarouselComponent, Expected 0 arguments, but got 1. The strange thing is that I am not using the SlideComponent/CarouselComponent anywhere in my application.  In fact these errors only started appearing when I used the mdbChartdirective on a canvas element for a bar chart.  Here is the module for my exported module:

Start your code here

@NgModule({ imports: [ CommonModule, UiModuleWrapper, UtilitiesModule, MDBBootstrapModule.forRoot(), ToastrModule.forRoot() ], schemas: [ NO_ERRORS_SCHEMA, CUSTOM_ELEMENTS_SCHEMA ], declarations: [ CustomComponents ], exports: [ CustomComponents ] }) export class CustomUIModule { } I am importing this CustomUIModule into my app's app.module.ts, and it does run as expected, it's just not packaging correctly.  Do you guys have any suggestions as to what might be wrong? Kind regards GianPiero
