Problem

When creating a Jira Story from a Confluence whiteboard, the operation fails if the issue type includes a "Message Field" custom field. This occurs even though the "Message Field" is not required and is intended only for user guidance. The error "Operation value must be a string" is returned, preventing issue creation.

Environment

• Confluence Cloud (Whiteboards)
• Jira Cloud (Story issue type with "Message Field" custom field, not required)

Steps to Reproduce

1. Open a Confluence whiteboard.
2. Add a sticky note.
3. Select "Convert to Jira issue".
4. Choose a Jira project and select the Story issue type that includes the "Message Field" (not required).
5. Attempt to create the issue.

Expected Results

The Jira Story should be created successfully, with the non-required "Message Field" ignored during creation.

Actual Results

The creation fails with the following error:

Operation value must be a string

The issue is not created. This only occurs when creating from a Confluence whiteboard; creating the same Issue or Story directly in Jira works as expected.

Workaround

• Create the Jira Story directly in Jira, bypassing the whiteboard integration.
• Alternatively, consider using a different custom field type (e.g., "Text field (multi-line)") if possible.

Notes

• The "Message Field" is not required in the workflow or field configuration and is intended for display/guidance only.
• The problem occurs even when the "Message Field" is not required.
• Similar to CONFCLOUD-78496, but this affects non-required fields as well.
