UNSOLVED Change configuration for Calendar

[uatuba]

I updated my MagicMirror, and apparently there was a breaking change in the calendar configuration for some reason, because when I remove it from my config, the mirror works. Here’s what I have:

                {
                        module: "calendar",
                        header: "Upcoming Events",
                        position: "top_left",
                        config: {
                        timeFormat: "absolute",
                        getRelative: 0,
                        urgency: 0,
                        showEnd: false,
                        maximumEntries: 10,
                                calendars: [
                                        {
                                                symbol: "calendar-check-o ",
                                                url: "webcal://p62-calendars.icloud.com/published/2/hkgslOqBKyBGC-S....
                                        }
                                ]
                        }
                },

Can someone tell me where I’ve gone wrong?
