Error: no custom:calendar-card

[haegar33]

Following the ReadMe:

type: custom:calendar-card
title: "My Calendar"
progressBar: true
entities:

• calendar.mycalendar

was entered in a custom card editor. I am sure something is missing? This should be explained in the help section

doesnt look like it was installed. install via HACS

[haegar33]

Well it was installed via HACS... I realize that all custom: elements are very shaky in HA. Even if you set the "resource" URLs, restart HA 5 times, a new custom card is hardly recognized in Lovelace. And even worse, if for one moment this is the case, I can have 3 different error message in 3 different browsers!
I wonder about the underlaying structure of Javascript elements and how they are handled by HA? I never had so much incompatible javascript errors before.
I can also see many users in the forum with the same problem.

• Should an installation via HACS be more "stable"?
• Should I try to install your script manually?
• I am using the UI Editor for Lovelace, better with a manual ui-lovelace.yaml?
• When using the UI Editor and press the large orange plus button I get a some custom cards presented in the list, your calendar-card is not showing up...
• In the HACS control panel->Frontend your calendar-card is showing up as loaded and ready to use...

The resource URL is (as installed by HACS):
/hacsfiles/calendar-card/calendar-card.js

you can try installing manually. I use this card and I've had no issues through all the updates in the past year.

well after some reinstallation and re-configs (now HA on plain unix, no hass.io) the card appears to be "detected" and loaded.
However now there are java sctrip error messages:

(e.entities||[]).map is not a function. (In '(e.entities||[]).map(e=>e.entity||e)', '(e.entities||[]).map' is undefined) type: 'custom:calendar-card' title: Test entities: calendar.privates
