Error executing a trigger ORA-04092: Unable to trigger

I have the following problem: - I can not execute a job (Scheduling) after an insert retrieved by the trigger.

  

Line 2: ORA-04092: Not possible on a trigger ORA-06512: in   "SYS.DBMS_ISCHED", line 135 ORA-06512: under "SYS.DBMS_SCHEDULER", line   271 ORA-06512: under "TRG_GET_LAST_INSERT", line 9

create or replace TRIGGER trg_get_last_insert
BEFORE INSERT
  ON TB_TOKEN
  FOR EACH ROW 

DECLARE
vToken NUMBER;

BEGIN

   SELECT ID INTO vToken FROM TB_TOKEN WHERE ID = ( SELECT MAX(ID) FROM TB_TOKEN );
   IF vToken IS NOT NULL THEN

        dbms_scheduler.create_job ( 
            job_name => 'TESTE_JOB', 
            job_type => 'PLSQL_BLOCK', 
            job_action => 'BEGIN 
                               DELETE FROM TB_TOKEN WHERE ID = ' + vToken + '
                            END;COMMIT;', 
            enabled => true, 
            start_date    => sysdate + 1/24,
            repeat_interval=> null
        ); 



   END IF;

END;

Does anyone know how to do this? The idea is to pass the parameter that is rescued and delete it after 1 hour .
