Kibana API Action and connector APIs returning 404

Question

I'm trying to use the actions and connector endpoints of the kibana api and its giving me 404, but things to do with listing spaces work fine

https://www.elastic.co/guide/en/kibana/7.x/actions-and-connectors-api.html

curl --location --request GET 'https://kibana.<acme>.com/api/actions/connector_types' \
--header 'Authorization: Basic <redacted>'

{ "statusCode": 404, "error": "Not Found", "message": "Not Found" }
