I followed the steps of Mr. Thokala “Seamless PDF Generation with Oracle APEX and OCI Document Generator” using Oracle OCI Free. When I try to create the credential using apex_instance_admin.create_cloud_credential, I get the following errors:
ORA-20987: APEX - The DBMS_CLOUD package is not available on this system.
ORA-06512: at "APEX_240100.WWV_FLOW_INSTANCE_ADMIN", line 1940
ORA-06512: at "APEX_240100.WWV_FLOW_ERROR", line 1123
ORA-06512: at "APEX_240100.WWV_FLOW_ERROR", line 1581
ORA-06512: at "APEX_240100.WWV_DBMS_CLOUD_INT", line 45
ORA-06512: at "APEX_240100.WWV_FLOW_INSTANCE_ADMIN", line 1915
ORA-06512: at line 2
Error at Line: 7 Column: 0.
I assume that the DBMS_CLOUD package is installed since I am using the autonomous database that comes with the APEX instance on oracle cloud.
