Solve the following python programming problem given the following code:
@ wsgi.response (204) 
def delete(self, req, gid, pid) : 
    def _delete_children(context, gid, pid) : 
        processes = db.process_get_all (context, gid, { 
            'ppid' : pid, 
}) 
        for process in processes : 
            _delete_children (context, gid, process ['pid']) 
            _delete (context, gid, process ['pid'], process ['nova_instance_id']) 
return 
def _delete(context, gid, pid, nova_id) : 
        self.manager.process_delete (context, nova_id) 
        try : 
            db.process_delete (context, gid, pid) 
except exception.NotFound as e : 
            LOG.exception (e) 
self._uuid_check (gid, pid) 
    context = req.environ ['rack.context'] 
    try : 
        process = db.process_get_by_pid (context, gid, pid) 
except exception.NotFound as e : 
        raise webob.exc.HTTPNotFound (explanation = e.format_message ()) 
_delete_children (context, gid, pid) 
    _delete (context, gid, self, process ['nova_instance_id']) 

    
    

    Fix the buggy line: _delete (context, gid, self, process ['nova_instance_id'])
assistant
#Here is Python code to fix the buggy line: _delete (context, gid, self, process ['nova_instance_id'])
.

_delete (context, gid, pid, process ['nova_instance_id'])
