i am a bit stuck right now. What i want to achieve is doing a request to the api that returns all posts that do not have a taxonomy assigned.
I can do this request to get posts from a specific taxonomy:
And i know i can exclude this taxonomy as well to get all but those posts:
But i have posts that actually represent my_taxonomy as an empty array like:
my_taxonomy = 
And i want to get all those posts without the need to exclude ALL other taxonomies in the request. Basically it is possible in WordPress by querying in PHP like so:
'operator' => 'NOT IN'
but i don't really want to write my own REST method just to do this request. Is there a way to achieve this with the default REST possibilities?
I tried already requests like
None of them work actually.
