Setting Post `output` to `false` exception in React Admin on missing `owl:Nothing` reference

[rvanlaak]

API Platform version(s) affected: 4.2.2

Description

With output: false on a Post operation on a resource the documentation points to owl:Nothing and that leads to a failure on the React Admin documentation parsing.

How to reproduce

Set Operation output to false. In my situation the input is a DTO command and messenger is set to true.

Possible Solution

This likely relates to \ApiPlatform\Hydra\Serializer\DocumentationNormalizer::getHydraOperation based on the $outputClass, and owl:Nothing not being defined in the documentation yet.
