Django Celery 计划任务崩溃

Question

Im trying to run a scheduled task on my Django project that is hosted on Heroku, however my task keeps crashing and I dont know how to fix this. Here is the error message bellow I'm getting in the error logs. I have in my settings.py my timezone set to 'America/New_York' and I even tried added the time zone as well in the celery.py to be the same to try to troubleshoot it but has no affect on it. I appreciate the help. Thanks

2020-09-29T14:42:58.149201+00:00 heroku[beat.1]: State changed from starting to up

Answer 1

So the solution was i had to add in settings.py

#Time Zone
USE_TZ = True    <--- Added
TIME_ZONE = 'America/New_York'

Heroku on Settings and Show Variables

TZ America/New_York
