204 Status code for nil returns

[jzillmann]

I have an endpoint which either returns an entity or not.
Instead of returning a 404 I would rather return a 204 which isn't treated as error in the frontend, which is good since the absence of the entity is an expected state.

Reading https://huma.rocks/features/response-outputs/ my only seems to be the Status field in the struct, which is dislike.
Any other option for me like a middleware doing if returnValue = nil... ?
