Celery multiprocessing issues on ubuntu based image

DO’s app platform fails to start up my celery app in prefork pool when using ubunut based image. From python docker repo I used python:3.8-slim. During deployment step I can see the workers throw the following error every time.

Traceback (most recent call last):

For testing purposes I switched to python:3.8-alpine and was able to run the app with no issues, but for my current application apline distro is not suitable. How can I resolve this issue without specifying --pool=gevent for celery ?
