Looking at upgrading ORDS from 20 to 23 and came across this:
Oracle APEX 22.1 and onwards no longer natively supports the serving of APEX Based Restful Service Modules. Existing APEX Based Restful Service Modules must be migrated to ORDS Resource Modules in order to avoid loss of service.
We have used the APEX UI, specifically the RESTFul Services screen under the SQL Workshop menu to create Modules ("ORDS Modules") protected by Privileges that serve JSON through one of our APEX URL's (Weblogic server running ORDS).

Is that an APEX-based RESTFul Service Module that needs to be migrated to an ORDS Resource Module (and presumably managed by SQL Developer Web)?
