"Missed comma between flow collection entries" error in Calendar page.yaml

Line 23 in 5469b35

{{ (data | fromjson)['calendars'] }}

Final entities line should be: entities: { { (data | fromjson), ["calendars"] } }

Same error message with me in the fan-control addon. But when I set the comma and save, Visual Studio puts a space between all { and I get the error message in the dashboard:
invalid key: "['entity']" in "/config/dwains-dashboard/addons/rooms/fan-control/button.yaml", line 5, column 0
So I guess I have to live with the error.
