Although macro displays a red banner with the message "Something went wrong" but the Jira roadmap is displayed correctly. Also if you update the plan in Jira same gets refreshed in Confluence.

But the pop up seems to be annoying or confusing making end user think some issue with macro. 

This is not an issue using Jira versions lower than 9.13+

Workaround

Use Jira versions lower than 9.13+

OR

On Jira side disable the newsletter-signup-tip module. 

1. Access to your Jira instance
2. Navigate to Administration (⚙) > Manage apps > Manage apps.
3. Select User-installed in the dropdown menu and change it to System to see the list of system apps.
4. Find Atlassian Jira - Plugins - Header Plugin in the list of apps and expand it.
5. Expand the list of modules.
6. Find and disable the newsletter-signup-tip module. (Note that there are two very similarly named modules, newsletter-signup-tip and newsletter-signup-tip-init, and only the former needs to be disabled.)
