Datapoint failure running every sample project in PAT on Kubernete Cluster on AWS

edit

I am trying to run some of the PAT 3.4 sample projects on a Kubernete cluster on AWS. I have deployed the cluster and installed the Helm chart according to the instructions here. Everything seems to be working when I run kubectl get pods

I can connect to the server in the PAT application, but when I run the algorithmic analysis each datapoint fails with the error datapoint failure. This is an extract of a datapoint log

I am not a docker expert, let alone a kubernete one, but when I login in the actual EC2 instances for the worker nodes I would expect to find this file /usr/local/bin/openstudio, but it does not exist.

Any suggestion?
