Issue Summary

Currently, there is no REST API endpoint available to retrieve the labels stored in a custom field of type "Labels" created by a customer. This limitation prevents users from programmatically accessing the values stored in these custom fields.

Steps to Reproduce

1. Create a custom field of type "Labels".
2. Add this field to a screen.
3. Add some labels to the field in an issue.
4. Attempt to retrieve the labels using the following REST API endpoints:

• The Jira Cloud platform REST API

• The Jira Cloud platform REST API (Note: This endpoint only works for the system "Labels" field, not for custom fields.)

Expected Results

A dedicated REST API endpoint exists to fetch the labels stored in a specific custom field of type "Labels" created by a customer.

Actual Results

There is currently no REST API available to retrieve the labels stored in a custom field of type "Labels". The existing endpoints only support the system "Labels" field.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
