Error: nil pointer evaluating tls.enabled when installing Keycloak with Helm"

[lucamiano]

Hi, while executing the script i get this error once i get to keycloak installation
#Install and configure keycloak
Release "keycloak" does not exist. Installing it now.
Error: template: keycloak/templates/tls-secret.yaml:45:8: executing "keycloak/templates/tls-secret.yaml" at <include "keycloak.createTlsSecret" $>: error calling include: template: keycloak/templates/_helpers.tpl:298:18: executing "keycloak.createTlsSecret" at <.Values.tls.enabled>: nil pointer evaluating interface {}.enabled

Any solution?
