after upgrading from 7.7.0 to 8.0.0.dev0, sentry health api /_health/?full=1 reports {"healthy":{"CeleryAppVersionCheck":false,"CeleryAliveCheck":false},"problems":["Background workers haven't checked in recently. This can mean an issue with your configuration or a serious backlog in tasks.","Celery workers are referencing a different version of Sentry (8.0.0.dev0 vs 7.7.0)"]}
and the website has two red bars for these warning, but the reporting mechanism seems work well, and there are no warning/error records in logs.
Do these warnings have serious problem? how can I fix these warnings? (I've totally removed old sentry files in /usr/local/lib/python2.7/site-packages/sentry* and made a fresh installation)
Thanks!
