Hi
I have been looking through all the questions, and tutorials for Django and Celery for App Platform but I can’t seem to see anything that is helpful.
The Celery work seems to start, and then dies with a fatal error. I have pasted what is happening below.
If anyone has any ideas that would be most appreciated!
Kind regards,

Hi, its 2022 - is this issue resolved. Is there a written tutorial someone can point me to that covers how to get celery working on Django App Platform?
I’m interested in this feature as well. Any update from the DO team?
