Solve the following python programming problem given the following code:
def _test_check_repository_error(self, http_status, payload, expected_error, **kwargs) : 
    def _http_get(service, url, * args, **kwargs) : 
        if (http_status == 200) : 
            return (payload, { 
                
}) 
else : 
            raise HTTPError (url, http_status, '', { 
                
}, StringIO (payload)) 
account = self._get_hosting_account () 
    service = account.service 
    self.spy_on (service.client.http_get, call_fake = service) 
    account.data ['authorization'] = { 
        'token' : '123', 
} 
    try : 
        service.check_repository (** kwargs) 
        saw_exception = False 
except Exception as e : 
        self.assertEqual (six.text_type (e), expected_error) 
        saw_exception = True 
self.assertTrue (saw_exception) 

    
    

    Fix the buggy line: self.spy_on (service.client.http_get, call_fake = service)

#Here is Python code to fix the buggy line: self.

self.spy_on (service.client.http_get, call_fake = def _http_get()
