"A template must be specified"
Ran into an interesting scenario in Director that I have not solved yet but will (hopefully) today.
Created a cluster via the python sdk and when attempting to repair a node in any instance group I get "A template must be specified". There is nothing in the logs and this instance group only contains gateway roles for HDFS and YARN.
This is Director v6.1 and there are no "templates" in the templates tab since everything was programmatically generated.
