psychedelicious 23d9d58c08 fix(nodes): fix bugs with serving images
When returning a `FileResponse`, we must provide a valid path, else an exception is raised outside the route handler.

Add the `validate_path` method back to the service so we can validate paths before returning the file.

I don't like this but apparently this is just how `starlette` and `fastapi` works with `FileResponse`.
