while installing the prerequisite charts got the following error in

datahub-prerequisites-cp-schema-registry

pod. I am trying to install it in EKS.

Just wanted to double check if you faced this before and in case have a resolution for this, before I start the debug process.

Has kafka spun up correctly? are the kafka/bootstrap pods and kafka service are all healthy?

here are the ouput of other pods.
