每当芹菜要执行任务时，我都会遇到异常
Pool callback raised exception: ContentDisallowed('Refusing to deserialize untrusted content of type pickle (application/x-python-serialize)',)
Traceback (most recent call last):
File "/Users/fulfil/venv/lib/python3.5/site-packages/kombu/utils/objects.py", line 42, in __get__
return obj.__dict__[self.__name__]
KeyError: 'chord'
During handling of the above exception, another exception occurred:

我正在使用Celery == 4.1.1（latentcall）和kombu == 4.2.1版本 有人可以帮我吗？
