Getting NoMethodError after deployment using generic-k8s method

[ashleymichaelwilliams]

Full disclosure, I haven't used this project in quite some time and my fork of the code became outdated with deprecated ruby dependency packages. While trying to get a more recent snapshot of the code, I deployed the project using the latest code from the main branch. The default page loads eventually after a couple of refreshes and the DB is populated with records and schema. However the problem is I get this error message when clicking the Cart button or trying to navigate to the /admin url.

I have tried using all three ads-service folders source code (broken, fixed, errors) with the same result. Also tried alternate code for the other services (discount and store-frontend) with no success.

Something to note is I'm not running Datadog on my cluster presently, but i would imagine this would be fine. I do see errors reported in the logs.

Any help would be greatly appreciated. Happy to provide more details if necessary.

I tried disabling Datadog's capabilities (ie. Tracing, profiling, Log Injection) on the Python containers (ads, discount) using the following vars.

          - name: DD_LOGS_INJECTION
            value: "false"
          - name: DD_ANALYTICS_ENABLED
            value: "false"
          - name: DD_PROFILING_ENABLED
            value: "false"
          - name: DD_TRACE_ENABLED
            value: "false"

Seemed to clear up the Connection refused errors I was getting rhe logs.

Found the related event in the container log output, which should give some detail around environment config as well as URI path. 🤷🏼

Also when i navigate to the advertisements:5002/ads my browser returns the three items in json to my browser. Seems the flask endpoint is responding just fine.
