Ruby AWS-SDK: How to list the parent checks of a health check

Question

I have a job that cleans out unused health checks. Some of them cant be deleted if they have a parent check resulting in the error:

Invalid parameter : Health check SOMEHEALTHCHECKID is still referenced from parent health check(s): SOMEHEALTHCHECKID-PARENT

How can I list the parents of a health check? I would like to be able to obtain the id of the parent check in a method that is more stable than parsing the error message string.

My solution was to collect all the health checks in route53 and parse them for any that matched the CALCULATED config type:

check[:health_check_config][:type] == "CALCULATED"

Then after getting the Aws::Route53::Errors::InvalidInput error during health check deletion, I would search through my parent check collection to see if any parent check included the failed check in its child_health_checks array:

parent_checks = parents.select{|parent_check| 
  parent_check[:health_check_config][:child_health_checks].include?(check[:id])
}

I could then delete all the matching parent checks and retry the regular deletion after.
