I am guessing the error we are seeing now is because we need a newer version of the confluent-kafka package now that we are using the confluent images. We are supporting the same versions of kafka but maybe the interaction is different.

We probably need to bring a newer one now that we are using confluent kafka and dropped bitnami?

Note: I assumed that they might have a python client with versions matching the confluent platform version we are using (as is commonly done), but looking at the client versions this is not the case. 2.11.1 seems to be the latest one so we should be good there. It was a wild guess about why tests could be failing.

No, but the failure is expected since the bumped dependency is not yet built at this point so it's pulled the image from it's upstream repository. Once the dependency resolution gets merged we'll see these failures resolve itself.
