This is very likely a server issue. The error reported in the Nextcloud log happens in the CalDAV server code, which is built into Nextcloud server. Please report the issue there: https://github.com/nextcloud/server/issues and link it here. Thanks!

Edit: You could try to confirm this by using a different client: E.g. Thunderbird or any other CalDAV client.

@raimund-schluessler , my debbug says

the request function calls _suggestUri() which replaces my '테스트' to '테스트'.toString().toLowerCase().replace(/\s+/g, "-").replace(/[^\w\-]+/g, "").replace(/--+/g, "-").replace(/^-+/, "").replace(/-+$/, "");

In short, '테스트'.toString().toLowerCase().replace(/\s+/g, "-").replace(/[^\w\-]+/g, "") is ""

[raimund-schluessler]

Hm, you are right, sorry for my hasty conclusion and thanks for debugging this!

Checking if suggestUri is empty and replacing it in this case like the calendar app does it https://github.com/nextcloud/calendar/blob/master/js/app/utility/stringUtility.js#L49-L51 might already be enough.

As a workaround, you can create a calendar with korean names using the calendar app.

[homokimchi]

I've learned with this. The pleasure is all mine. Thanks :-)

[Mirokko]

Creating new list in Russian language not working either.

[raimund-schluessler]

Will be fixed in the https://github.com/nextcloud/tasks/tree/vue branch
