A component passed as kbqComponent is created from the root environment injector, not from the component that called KbqModalService. Anything the caller provides itself is therefore invisible inside the modal: component-level services, tokens from a route or a lazily loaded module, and providers that reach the caller only through NgModules listed in its standalone imports — DateAdapter, KBQ_DATE_FORMATS and DateFormatter among them.

To make them available, pass the caller's injector to modalService.open; it becomes the parent of the modal content's injection hierarchy. Content passed as a TemplateRef is unaffected — it keeps the injector of the component that declared it.

A missing dependency surfaces as NullInjectorError: No provider for …, thrown while the modal content is being created.
