Невозможно связать исключения в Python

0 голосов
/ 01 мая 2020

То, что я пытаюсь сделать, - это цепочка моих исключений, поэтому, когда Flask werkzeug.exceptions.HTTPException повышается, оно вызывает мое пользовательское исключение exception.api.Error.

Однако я продолжаю получать следующую ошибку, и я Я не уверен, как это исправить. Есть предложения? 

from werkzeug.exceptions import HTTPException
import exception.api as exception

app = Flask(__name__)

@app.errorhandler(exception.Error)
def ExceptionAPI(e):
    r = jsonify( e.response )
    r.status_code = e.status
    return r

@app.errorhandler(HTTPException)
def HTTPException(e):
    raise exception.Error(e.code)

Файл: исключение / api.py 

from exception.message import Message

class Error(Exception, Message):
    message = None
    status = None
    response = None

    def __init__(self, message=None, status=None):
        Exception.__init__(self)
        if message is not None:
            m = self.getMessage(message)
            self.response = {'e': m['public']}
            if not status:
                self.status = m['status']
            else:
                self.status = status
        else:
            if status is not None:
                m = self.getStatus(status)
                self.response = {'e': m['public']}
                self.status = status
            else:
                logging.error('else')
                m = self.getStatus(500)
                self.response = {'e': m['public']}
                self.status = m['status']

Я пробовал: raise exception.Error(e.code) from e также приводит к ошибке
