Python 芹菜共享_任务参数解析错误

我正在使用芹菜4.2.0和Django来调度rabbitmq中的新任务，在解析参数时它会随机失败。 我的代码如下所示：

for param in serializer.validated_data['parameters']:
        run_task.delay(param_name=param)

其中，参数是int的列表，并通过序列化程序验证来确保

@shared_task
def run_task(param_name: int) -> None:
    obj= Obj.objects.filter(param=param_name)
    ...

在UTs下，当我调用此

run_task

和

cellery_task\u ALWAYS\u EAGER=True

时，一切正常。在真实环境中，此任务有时运行正常，有时因服务器错误而失败：

    File "/usr/lib/python3.6/site-packages/rest_framework/decorators.py", line 53, in handler
    return func(*args, **kwargs)
  File "/opt/app/compliance/jobs/views.py", line 30, in create_task
    run_task.delay(param_name=param)

    return self.apply_async(args, kwargs)

    return self.amqp.producer_pool
  File "/usr/lib/python3.6/site-packages/celery/app/amqp.py", line 612, in producer_pool
    self.app.connection_for_write()]
  File "/usr/lib/python3.6/site-packages/kombu/utils/collections.py", line 34, in __getitem__
    h = eqhash(key)
  File "/usr/lib/python3.6/site-packages/kombu/utils/collections.py", line 25, in eqhash
    return o.__eqhash__()
  File "/usr/lib/python3.6/site-packages/kombu/connection.py", line 629, in __eqhash__
    repr(self.transport_options))
  File "/usr/lib/python3.6/site-packages/kombu/utils/collections.py", line 16, in __init__
    self.hashvalue = hash(seq)
TypeError: unhashable type: 'set'

我理解错误本身，但当我只传递一个简单且可解析的参数（非集合）时，它为什么会出现在这里。有人知道如何让它持续工作吗

谢谢

在失败的情况下，您能打印

param

的值吗？在发送之前，我有一行：

LOGGER.info（'sending request for param%d'，param）

，它会生成

sending request for param 17
