So, you can keep raising **FastAPI**'s `HTTPException` as normally in your code.

But when you register an exception handler, you should register it for Starlette's `HTTPException`.

This way, if any part of Starlette's internal code, or a Starlette extension or plug-in, raises a Starlette `HTTPException`, your handler will be able to catch and handle it.

You can register crawling targets in the Admin UI on the (Web, File, Data Store) crawler configuration pages, and then start the Crawler manually on the [Scheduler page](https://fess.codelibs.org/15.0/admin/scheduler-guide.html).
