How to update sub-task siblings based on a sub-task custom field value

[Deleted user]

In short, we have a transition on sub-tasks that we would like to run on a specific set of sub-tasks depending on the value of a multi-select checkbox custom field on a sibling sub-task.

I'm trying to:

1. Get the value of the checkbox that is presented on a transition on the "special" sub-task
2. run some conditional code based on the values found that builds another list of issue types and transition ids
3. use this dynamically generated list to update sibling sub-tasks.
4. link the sibling sub-tasks to the "special" sub-task

I can't seem to get the parent key/id.
I'm not sure if I am creating the list correctly (is it .add or .push?)
The 'for(value in selectedActivities)' seems wrong

We are on Atlassian Cloud using a Scriptrunner post function.

Here is what I have so far (many cases omitted):

def amdSubtask = issue.key // The issue key of the study amendment subtask on which this script will run as a post function
def StudyIssueKey = issue.getParentObject()?.getKey() // get the parent issue key

// def selectedActivities = ["Protocol", "Budget", "Contract", "Coding", "Billing Grid", "Bellevue"]
def selectedActivities = issue.fields.customfield_11711 // get the set if values selected in the "Study Activities" custom field
logger.info("SELECTED " + selectedActivities)

def aList = [] // create a map of issue types to transition , and the transition ID for Initiate Study Amendment

for(value in selectedActivities)
 // If Selected Activity = "Protocol" then add the following issue types to the aList
 switch (value){
 
 case "Protocol":
 aList.add("Protocol - Development":11)
 break;
 case "Budget":
 aList.add("Budget":11)
 break;
 }
 
 
logger.info("List of Subtask Types: " + aList)

// Retrieve all the subtasks of the parent
def allSubtasks = get("/rest/api/2/search")
 .queryString("jql", "parent=${StudyIssueKey}") 
 .queryString("fields", "issuetype") 
 .asObject(Map)
 .body
 .issues as List<Map>
logger.info("Total subtasks for ${StudyIssueKey}: ${allSubtasks.size()}")


//Now run the transition on the subtask issue types in the map
for (subtask in allSubtasks) {
 // get subtask key
 def subtaskKey = subtask.key
 // Transition issue if ID is not 0, otherwise continue with loop
 if (aList.getAt(subtask.fields.issuetype.name)){
 post("/rest/api/2/issue/${subtaskKey}/transitions")
 .header("Content-Type", "application/json")
 .body([
 "transition": [
 "id": aList.getAt(subtask.fields.issuetype.name) // The transition might be 11 for all, in which case, we can just use 11 and remove transition id from list
 ]
 ])
 .asString() 
 logger.info(subtask.fields.issuetype.name + " do transition " + aList.getAt(subtask.fields.issuetype.name))
 
 //Link to the Study Amendment subtask
 post('/rest/api/2/issueLink')
 .header('Content-Type', 'application/json')
 .body([
 type: [ name: "Amendment" ],
 outwardIssue: [ id: amdSubtask ], // "is Amended by (amdSubtask)
 inwardIssue: [ key: subtaskKey ] // is Amendment to (subtask)
 ])
 .asString()
 }
 else{
 logger.info("Transition not available " + subtask.fields.issuetype.name) 
 }
}
