Solve the following python programming problem given the following code:
def test_get_errors_to_process_max_limit(self) : 
    date = datetime.utcnow () 
    def make_error(id, current_attempt, total_attempts) : 
        error = create_error ({ 
            'id' : id, 
}) 
        error.date_next_attempt = date 
        error.current_attempt = current_attempt 
        error.total_attempts = total_attempts 
        error.save () 
make_error ('to-process1', settings.PILLOW_RETRY_QUEUE_MAX_PROCESSING_ATTEMPTS, settings.PILLOW_RETRY_MULTI_ATTEMPTS_CUTOFF) 
    make_error ('to-process2', 0, (settings.PILLOW_RETRY_MULTI_ATTEMPTS_CUTOFF + 1)) 
    make_error ('not-processed1', (settings.PILLOW_RETRY_QUEUE_MAX_PROCESSING_ATTEMPTS + 1), settings.PILLOW_RETRY_MULTI_ATTEMPTS_CUTOFF) 
    make_error ('not-processed2', settings.PILLOW_RETRY_QUEUE_MAX_PROCESSING_ATTEMPTS, (settings.PILLOW_RETRY_MULTI_ATTEMPTS_CUTOFF + 1)) 
    errors = PillowError.get_errors_to_process (date, fetch_full = True).all () 
    self.assertEqual (len (errors), 2) 
    docs_to_process = { self.doc_id for e in errors } 
    self.assertEqual ({ 'to-process1', 'to-process2' }, docs_to_process) 

    
    

    Fix the buggy line: docs_to_process = { self.doc_id for e in errors }

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

docs_to_process = { e.doc_id for e in errors }
