How do we access Custom Metadata Types through Visualforce? I couldn't find any relevant article that covers this to the point. I have a requirement, where I need to reference the custom MDT and populate variable values in the VF page based on the MDT value. Have read that we could use remote objects to do that. Any help on that would be appreciated.
PS: We are not using any custom controllers for this VF page.

I am getting the attached error when I try to check the challenge 7 on Lightning Experience Reports & Dashboards Specialist superbadge.
I am using a new trailhead playground for this superbadge. Any kind of suggestion in resolving this is greatly appreciated.
