Inserting roadmap macro throws error upon review in a space Template created by user with confluence-user privileges

Issue Summary

Inserting roadmap macro throws error upon review in a space Template created by user with confluence-user privileges.

Steps to Reproduce

1. Create a user added to group Confluence-users who has confluence-administrator privileges but not the system administrator privileges
2. Login as above user
3. Go to Space tools>> Content Tools>>Templates>> Create a new Template
4. Create a Test Template
5. Insert macro "Roadmap planner"
6. Click on preview which throws the following error:

   Error rendering macro 'roadmap'
   Could not check permissions for page: Template Preview v.1 (0) no suitable delegate found.
   

7. Same error is present upon saving the Template
8. Enabling the system-administrators privileges within confluence-users group does not work either.

Expected Results

Roadmap planner macro should get inserted without any error

Actual Results

Error is thrown as depicted in attached screeshot

Workaround

Currently, only workaround that works is when user is mapped to system-administrators group. The error does not appear if user is part of system-administrators group.
