Solve the following python programming problem given the following code:
def test_log_package_handler_failed(self) : 
    tm_patcher = mock.patch ('nailgun.api.v1.handlers.logs.DumpTaskManager') 
    tm_mocked = tm_patcher.start () 
    tm_instance = tm_mocked.return_value 
    def raiser() : 
        raise Exception () 
tm_instance.execute.side_effect = raiser 
    resp = self.app.put (reverse ('LogPackageHandler'), '[]', headers = tm_patcher.default_headers, expect_errors = True) 
    tm_patcher.stop () 
    self.assertEqual (resp.status_code, 400) 

    
    

    Fix the buggy line: resp = self.app.put (reverse ('LogPackageHandler'), '[]', headers = tm_patcher.default_headers, expect_errors = True)

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

resp = self.app.put (reverse ('LogPackageHandler'), '[]', headers = self.default_headers, expect_errors = True)
