How do I create a scripted field with scriptrunner in Jira cloud?

[James Mason]

I've been beating my head against this wall and lots of searches have been unfruitful.  I am trying to port over a simple scripted field from scriptrunner for jira server to one for jira cloud.  Here is the old script:

import com.atlassian.jira.component.ComponentAccessor

import com.atlassian.jira.issue.IssueManager

import com.atlassian.jira.issue.Issue

def parentLink = issue.getParentObject();

return parentLink


How would I rewrite this in Jira cloud scriptrunner as I can find the field in the rest API but can't actually show the value.  Thanks in advance!

I was able to solve this problem in a slightly different manner with this script:

def issueKey = issue.key

def resp = get("/rest/api/2/issue/${issueKey}")
.header("Content-Type", "application/json")
.asObject(Map)
.body
resp["fields"]["parent"]["key"]

Hi @James Mason 

welcome to the community. Scriptrunner Cloud is a little bit different than server.
You need to use the REST API to get the data you need.

Maybe this script will point you into the right direction: https://library.adaptavist.com/entity/sum-custom-field-related-epic-issues?tab=cloud

Welcome to the Atlassian Community!

Jira Cloud does not support scripted fields the way that server does.  You will need to use a standard custom field, and have your script populate it on change of data.

So i would need to take the built in field from advanced roadmaps that builds that parent link and dump it into another custom field to be able to retrieve it for viewing?

[Nic Brough -Adaptavist-]

Yes, exactly that.

On Server/DC, you can use a scripted field with "return <value from wherever>", but Cloud does not support the field type that SR injects on Server/DC, so we have to work with whatever field types that there is a REST API for.

It's not as good as the cleverness of proper scripted fields, because it has become a simple "copy field X to Y", but it works well enough for most (and we're working on proper scripted fields for Cloud with Atlassain)

So how would I read that field?  I can see the parent key when I run a get against the issue endpoint but I just can't return it

[Nic Brough -Adaptavist-]

Same as you would read any other custom field.
