How can I use the built-in custom errors?

I am rather new to NodeJS, so forgive me for any basic errors.

That said, I've been trying to see if a thrown error is of type `AttachmentNotFoundError`. However, I don't think this error type is actually exported anywhere, and thus any attempt to use `instanceof AttachmentNotFoundError` results in `TypeError: Right-hand side of 'instanceof' is not an object` or `ReferenceError: AttachmentNotFoundError is not defined`.

Is there any way I can import this from `src/types/errors`? Thanks!
