Label details not showing in page storage format of Confluence page

Hi All,
We have created an automation to automatically create Confluence page whenever Jira issue got created.
For that we created a template in Confluence and added a label(tracker-record) to it.
With this template we created a sample page(where the label is automatically get added to the page) and copied the page storage format.
Then we converted the storage format to json and added that in our Jira Automation custom body to automatically create Confluence page using this template format.
But the information related to labels are not showing in the page storage format.
We were able to create the confluence page automatically whenever jira issue got created, but the labels (tracker-record)are not getting added to the pages as it is not there in the page storage format. Now we are adding the label manually.
The label details are not showing in the page storage format, even thought the labels are added in the page.

Is there any way to retrieve the label details so that we can add that in the custom body of our Automation.

Please help us to resolve this issue.

Thank you!
Regards
Arya
