Open Graph fields are not editable for the display page template

Issue

• I am not able to edit the Open Graph of the display Page Template on the Page Design Options. I receive an error in the log and the OG fields are greyed out.

Reproduction Steps:

1. Go to Design --> Page Templates --> Display Page Templates and create a display page template with Web Content Article as the "Content Type", and Basic Web Content as the "Subtype".

2. Click on the Page Design Options icon on the left side panel and click the "More Page Design Options" gear.

3. Click the "Open Graph" option.

Expected Result: The Open Graph should be editable with no issues.

Actual Result: The fields are greyed out and an error is thrown in the log:

ERROR [http-nio-8080-exec-5][JSPRenderer:66] Unable to render JSP /layout/screen/navigation/entries/open_graph.jsp
