Issue Summary

• This bug is not about supporting the custom field type "Message Custom Field", but about communicating properly this field is not supported when creating Jira Issues directly from Whiteboard.

Steps to reproduce

1. Create a custom field with type Message Custom Field (Edit) and make it required
2. Go to Confluence and open a Whiteboard
3. Select an element and try to create a Jira Issue
4. Select the project and the issue type where the new custom field is required.

Expected results

• Communicate that this custom field is not supported and suggest to create the issue directly on Jira as it already happens when trying to create the Jira Issue on a regular Confluence page:

Actual Results

• The custom field appears and allow users to edit it. However, it fails when clicking to create with a misleading error: Operations value must be a string

Workaround

• Create the Jira Issue directly on Jira.
• Alternatively, consider using a different custom field type like Text field (multi-line) instead.
