When there is an exception during the creation of a service or component during injection, a NullInjectorError is reported:
NullInjectorError: R3InjectorError(AppModule)[MyFailingService -> MyFailingService -> MyFailingService]:
NullInjectorError: No provider for MyFailingService!
But this error message is misleading, it should rather tell me that there is a provider, but the creation of the instance has failed.
