Solve the following python programming problem given the following code:
def test_no_instance_passthrough_404(self) : 
    def fake_compute_get(* args, **kwargs) : 
        raise exception.InstanceNotFound (instance_id = 'fake') 
self.stubs.Set (compute.api.API, 'get', fake_compute_get) 
    url = '/v2/fake/servers/70f6db34-de8d-4fbd-aafb-4065bdfa6115' 
    res = self._make_request (fake_compute_get) 
    self.assertEqual (res.status_int, 404) 

    
    

    Fix the buggy line: res = self._make_request (fake_compute_get)
assistant
#Here is Python code to fix the buggy line: res = self.

res = self._make_request (url)
