How do I find out why my angular tests fail in afterAll?

I have an angular 7 app which I recently wrote tests for. When executing them I run into an error in "afterAll".

If it were inside of one of the test-cases I could debug it easily. But in this case I don't know whats actually going wrong.

This is the relevant part of the console:

I already downgraded my jasmine-version to 2.99 as that seemed to work for other people with similar problems. But it didn't have any effect for me.

"TableBodyComponent" ist a component that is dynamically created and in the app.module.ts it is added to "entryComponents".

For all components that use it, I added it to "providers" in their respective spec-files.

Do I have to add "TableBodyComponent" somewhere else?

Am I doing something else wrong?
