      The error is due to 1) recent dcaegen2-service template change which is expecting new parameter - .Values.log.path to be set (cannot be null) - This will be addressed in DCAEGEN2-3093

      The helm generator should use "log.path" rather than "logDirectory" when it generates the values.yaml for a chart, if the microservice is writing logs to a directory (and not to stdout/stderr). Scope of this Jira will be address this item.
