market-api in caverns-1g952y7 is crash-looping, the same way it did in Chapter 1. This time, instead of swapping the image, give it what it asks for:

kubectl logs deploy/market-api -n caverns-1g952y7

Set the variable on the Deployment with kubectl set env. The rollout replaces the Pod. Then look at the whole environment from inside with kubectl exec deploy/market-api -n caverns-1g952y7 -- env.
