Resolution

This happens when anonymous is granted the permissions Overall/Read and Item/Discover but not Item/Read. This a mode that is used to force login redirects from job URLs. You can find more information about this in the article Q&A: Setting Up Role-based Access Control

The stacktrace may actually exposes a bug for a particular component in Jenkins that does not impersonate as SYSTEM user when accessing an item. A non-exhaustive list of issues is mentioned above. Please check on these JIRA to check if there is a fix implemented for it. If you are seeing a similar stacktrace as Please login to access job <itemName> but for a different component/scenario, please open a new Support request for review or directly file a new issue in JIRA.

Otherwise, a workaround is to remove the Item/Discover permission from the anonymous user.
