Deployment problem with config map for user_variable_substitution.py

[loneil]

Helm charts are looking for a file in a volume based on a configmap that is not found, causing oidc controller pod to fail on container creating.

Unable to attach or mount volumes: unmounted volumes=[custom-variable-substitution], unattached volumes=[], failed to process volumes=[]: timed out waiting for the condition

MountVolume.SetUp failed for volume "custom-variable-substitution" : configmap "vc-authn-oidc-variable-substitution-config" not found

Deploys successfully to dev now (and can see config files in /etc/controller-config and loaded by controller app)
Was an issue with the old breaking custom-variable-substitution volume still remaining after deploy and still causing the pod to not start up. Resolved that with @i5okie

(that should not be an issue with next helm release for test/prod as the breaking volume wasn't in any helm release)
