Issue Summary

When JSM and Confluence are integrated, JSM portal users that are not Confluence users can access Confluence. When these users access a page that contains the "Blog posts" macro, the macro will not display. Instead, an error message is shown in its place.

This is reproducible on Data Center: (unknown)

Steps to Reproduce

1. Integrate JSM & Confluence
2. Go to the knowledge base settings and enable "all logged-in users" for the space integrated.
3. Make sure the portal user is not a part of any group added to the space permissions.
4. In Confluence, create a blog on the space that was integrated with JSM.
5. Create a new page and insert a new "Blog posts" macro.
6. Using a portal user (customer) who doesn't have a license for Confluence, try to access the page that contains the "Blog Posts" macro.

Expected Results

The "Blog posts" macro should show the newly created blog post in that space.

Actual Results

The following error message displays:

Error rendering macro 'blog-posts' :
com.atlassian.confluence.api.service.exceptions.SSStatusCodeException: There was an illegal request
passed to XP-Search Aggregator API : HTTP/1.1 403 Forbidden

Workaround

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