Googleads AD Manger Unable to Open Database File in Flask Application Running on EKS with ArgoCD and Helm

Question

I am running a Flask application on EKS (Elastic Kubernetes Service) and managing it with ArgoCD and Helm. The application is using Google Ad Manager API. The error message is as follows:

I have tested the application in local environment and it works.
