prodcatalog pod goes in CrashLoopBackOff. Python Import error: cannot import name 'json' from 'itsdangerous' #12

I deployed the pods in EKS, frontend-node and proddetail seems running fine, but prodcatalogpod goes in crashloopbackoff.

Here is the pod log error. 

ec2-user:~/environment/eks-app-mesh-polyglot-demo/deployment (master) $ kubectl logs -f prodcatalog-5b85b57487-r4qp7 -n prodcatalog-ns

I think it's the issue of python docker image version of the way we are using pip ? Any suggestion or fixes?

I am seeing the same issue with Python 3.7

Even with the latest docker file which have python3.9, the issue still persists.

@uallu If you want to run just for temporary purpose, you can just use the public image which i found from helmchart public.ecr.aws/u2g6w7p2/eks-workshop-demo/product_catalog:1.0. I did the same. But if i am building the image with the dockerfile, issue still persists.
