What is the best way to handle 204 No Content HTTP response code?

[renatoi]

My API returns HTTP 204 on a bunch of occasions. This type of request doesn't have a body.

For example, if I do a GET request of entities and there are no entities, it returns 204. What should I do in this case?

Here's what I tried:

export const fetcher = async (input) => {
  const res = await fetch(input)
  const data = res.status === 204 ? null : await res.json()
  return data
}

The problem is that returning null doesn't work as NextJS seems to be hanging forever. So I have to return a valid JSON, even if empty. If I do this, the problem is that I'm tying this to all requests that use this fetcher and they might not expect the same object.

What should I do?
