Swagger does not work for nested objects (Apex, Oracle)

Question

I'm trying to generate swagger documentation via Oracle -Apex. Nested JSON objects either do not appear on documentation or cause error in swagger: errors

Is there any way for swagger to generate the correct documentation when there are nested objects in the code or can it be maybe overwritten somehow?

Here is an example of a JSON object that generates an error:

    v_sql_dane:='with
                    table_name3 as (   
                                     select
                                           rowid
                                     from table_name
                                     where 1 = 1 ' || v_where_firstname || v_where_lastname || v_where_gender || v_where_age || '  
                                     order by rowid
                                     OFFSET :b5 ROWS FETCH FIRST :b6 ROWS ONLY
                                  )  
                    select 
                           json_arrayagg(json_object(''TEMP_PERSON_UUID''             VALUE TEMP_PERSON_UUID, 
                                                     ''FIRST_NAME''                   VALUE FIRST_NAME,
                                                     ''LAST_NAME''                    VALUE LAST_NAME,
                                                     ''GENDER''                       VALUE GENDER,
                                                     ''AGE''                          VALUE AGE,
                                                     ''CALCULATED_DEGREE_TITLE''      VALUE CALCULATED_DEGREE_TITLE,                   
                                                     ''EMPLOYMENT_INSTITUTION_NAMES'' VALUE EMPLOYMENT_INSTITUTION_NAME format json 
                                                     returning clob ) 
                                         format json returning clob),
                            count(1)
                     from table_name3 
                              join table_name
                                    on column_name1 = column_name2';
    ```
