If you need to find issue entity properties for support purposes, you can get it through one of the following ways:

Jira API REST request

Open terminal (command-line interface) and execute the following curl command (please replace your-domain with your Jira URL and {issueKey} with valid Jira issue key):

curl --request GET \
  --url 'https://your-domain.atlassian.net/rest/api/2/issue/{issueKey}?properties=*all' \
  --user 'email@example.com:<api_token>' \
  --header 'Accept: application/json'

You need to replace an email address and API token with your own too.

You can also make the request through a tool like Postman app or similar.

Entity Property Tool plugin

1. Install Entity Property Tool plugin (it is not recommended to install it in a production environment)

2. Open issue page

3. Open Entity Property tab to see the details
