Invalid recursion selector value 'caas' in AEM 6.5
In AEM 6.3, we could expose our page content as JSON without using Content Fragments or Experience Fragments with the extension caas.json (e.g. localhost:4502/content/we-retail/us/en/men.caas.json) to 3rd party apps.
AEM 6.3 output :

After migrating to AEM 6.5, when we hit the same URL, we receive an error saying - Invalid recursion selector value 'caas'
AEM 6.5 error

In the release notes of AEM 6.5 we did not find any deprecation/removal of this feature.
Any idea as to why it's not working?
