Solve the following python programming problem given the following code:
@ mock.patch ('changes.config.queue.delay') 
@ mock.patch.object (HistoricalImmutableStep, 'get_implementation') 
@ responses.activate 
def test_finished(self, get_implementation, queue_delay) : 
    responses.add (responses.GET, SyncJobStepTest.ARTIFACTSTORE_REQUEST_RE, body = '', status = 404) 
    implementation = mock.Mock () 
    get_implementation.return_value = implementation 
    def mark_finished(step) : 
        step.status = Status.finished 
        step.result = Result.failed 
implementation.update_step.side_effect = mark_finished 
    project = self.create_project () 
    build = self.create_build (project = project) 
    job = self.create_job (build = build) 
    plan = self.create_plan (project) 
    self.create_step (plan, implementation = 'test', order = 0) 
    self.create_job_plan (job, plan) 
    phase = self.create_jobphase (job) 
    step = self.create_jobstep (get_implementation) 
    task = self.create_task (parent_id = job.id, task_id = step.id, task_name = 'sync_job_step', status = Status.finished) 
    db.session.add (TestCase (name = 'test', step_id = step.id, job_id = job.id, project_id = project.id, result = Result.failed)) 
    db.session.add (FileCoverage (job = job, step = step, project = job.project, filename = 'foo.py', data = 'CCCUUUCCCUUNNN', lines_covered = 6, lines_uncovered = 5, diff_lines_covered = 3, diff_lines_uncovered = 2)) 
    db.session.commit () 
    sync_job_step (step_id = step.id.hex, task_id = step.id.hex, parent_task_id = job.id.hex) 
    implementation.update_step.assert_called_once_with (step = step) 
    db.session.expire (step) 
    db.session.expire (task) 
    step = JobStep.query.get (step.id) 
    assert (step.status == Status.finished) 
    task = Task.query.get (task.id) 
    assert (task.status == Status.finished) 
    assert (len (queue_delay.mock_calls) == 0) 
    stat = ItemStat.query.filter ((ItemStat.item_id == step.id), (ItemStat.name == 'tests_missing')).first () 
    assert (stat.value == 0) 
    stat = ItemStat.query.filter...

    
    

    Fix the buggy line: step = self.create_jobstep (get_implementation)

#Here is Python program to fix the buggy line: step = self.

step = self.create_jobstep (phase)
