[filtered] format, calender view: TypeError: key.toUpperCase is not a function

[krabina]

Setup

• MW version: 1.31.5
• DB (MySQL etc.):MySQL 5.5.62-cll
• PHP version: 7.1.26 (fpm-fcgi)
• SMW version: 3.1.1 (143488d)
• SRF version: 3.1.0 (aa0649f)

Issue

Calender view not working.

Steps to reproduce In my tests, table view is working fine, just when I add the calendar view, the filtered format does not display anything other then the "loading" circle. When trying to recreate on Sandbox, the filtered format does not seem to work altogether: https://sandbox.semantic-mediawiki.org/wiki/Filtered/Calendar_view
