How to update the RAG Status via ScriptRunner

Overview

This section shows the instructions to use the ScriptRunner to update the RAG Status field automatically when the issue is overdue.

The Rag Status field doesn't show on the Automation for Jira.

Demonstration

Paste the following code into the Inline script field. This script will

execute JQL query to find a list of overdue issues and
set the RAG Status field of each matching issue to Red.
