Upgrading Redis on Heroku causing SSL errors in Celery

问题

我最近将我们的Heroku Redis从版本5.0升级到了7.0.11,现在在运行Celery时遇到以下错误:

celery.py文件:

from celery import Celery

app = Celery('endpoints')

# namespace='CELERY' means all celery-related configuration keys should have a 'CELERY_' prefix.
app.config_from_object('django.conf:settings', namespace='CELERY')
app.conf.redis_backend_use_ssl = {
                 'ssl_cert_reqs': 'CERT_NONE'
            }
app.conf.broker_use_ssl = {
                 'ssl_cert_reqs': 'CERT_NONE'
            }

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()

requirements.txt文件:

dj-database-url==2.0.0
Django==4.2.2
django-environ==0.9.0
django-storages==1.9.1
djangorestframework==3.14.0
django-cors-headers==3.5.0
django-parler==2.3
redis==4.5.5
celery[redis]==5.3.0

在升级之前一切都正常工作,但这个错误导致Celery立即崩溃。

Everything was working flawlessly prior to the upgrade, but this error is causing celery to crash immediately.

将此问题的解决方法是将 redis 的要求降级至 4.4.4 并从 celery 的要求中移除 [redis] 附加部分。

The solution to this issue was to downgrade the redis requirement to 4.4.4 and remove the [redis] extra from the celery requirement.
