Celery 工作人员在 Heroku 上崩溃

Question

我正在做一个 Django 项目，我已经推动了 Heroku，我使用了 Celery 作为后台任务。虽然 Celery 在本地运行良好，但在 Heroku 服务器上我发现 celery worker 崩溃了。我已在 settings.py 中正确设置 CLOUDAMQP_URL 并在 Procfile 中配置了工作人员配置，但工作人员仍然崩溃。

Procfile

web: gunicorn my_django_app.wsgi --log-file -
worker: python manage.py celery worker --loglevel=info

Settings.py

...
# Celery
BROKER_URL = os.environ.get("CLOUDAMQP_URL", "django://")
#CELERY_BROKER_URL = 'amqp://localhost'
BROKER_POOL_LIMIT = 1
BROKER_CONNECTION_MAX_RETRIES = 100
CELERY_TASK_SERIALIZER="json"
CELERY_RESULT_SERIALIZER="json"
CELERY_RESULT_BACKEND = "amqp://"
