I might be missing something but it appears that content for print or MS doc won't render.
To replicate use the contentbox docker image: ortussolutions/contentbox:lucee5
Contentbox 4.1.0+672 / coldbox 5.1.4+741
Navigate to Blog, first entry and then try to print.
The default theme has a drop down box with an option to print or pdf the content. Selecting print on a page results in "Oopsy! - The page you requested: /my-first-entry.print".
The expected result is content formatted for printing as per the themes layout pages_print.cfm. (The same happens for .doc content type).
Also adding .print or .doc to the page URL errors. eg /about.print
This issue also exists in 4.2...
