Calendar format query produces exception

[freephile]

Setup

On the website https://www.semantic-mediawiki.org/wiki/Help:Calendar_format

Issue

Clicking the link in the Example section (leads to this page) produces a SubSemanticDataException Fatal exception

The exception message is:

[3077da85100755f242b2e36a] 2024-06-12 14:51:32: Fatal exception of type "SMW\Exception\SubSemanticDataException"

(Note: I left an edit comment in the wikitext of the Help page next to the query)

Note that this is a dated instance. @freephile It will be great if you could reproduce on https://sandbox.semantic-mediawiki.net/wiki/Main_Page
