mediaMicroservices in K8 cluster: lua entry thread aborted: runtime error: unknown reason

[abmuslim]

I deployed the mediaMicroservice in my 3-node Kubernetes cluster. When trying to register movies and cast information using the following command:

python3 scripts/write_movie_info.py -c <path-to-casts.json> -m <path-to-movies.json> --server_address <nginx_server> && scripts/register_users.sh && scripts/register_movies.sh

The command runs successfully and outputs 18194 casts finished, 1000 movies finished. However, when I check the logs of my nginx-web-server pod, I see the following errors:

k logs nginx-web-server-579975cd6-9n59z -c nginx-web-server -n test --tail 50
