MultiExcerpt Macro disallowed to impersonate the user because 'no valid active user exists'
create a page in Confluence and use the MultiExcerpt Include macro
Access the Confluence page from your Jira Service Desk
As an anoymous user or as a service desk agent user the page renders fine
As a customer user who is NOT in your basic profile in JSD the page renders an error for the MultiExcerpt macro:
The issue is for all Includes, MultiExcerpt Include, Fast inline, & Fast Block. Jira users & anonymous users all see the page just fine. Portal users cannot see the include.
Portal users who do not have basic JSD user profiles can access the site in incognito mode (if the page is available to anonymous users)
