Hello @tleak26,

Seems your app env is lacking psycopg

Traceback (most recent call last):
File “C:\Users\tleak\Lib\site-packages\django\db\backends\postgresql\base.py”, line 25, in
import psycopg as Database
ModuleNotFoundError: No module named ‘psycopg’

So I guess your docker image doesn’t have psycopg.

Can you share your Dockerfile?

Maybe you will find some relevant stuff here.

Cheers
