Worrying looking warning messages

I am on ubuntu 22.04 and thunderbird 102.4.0

When I run thunderbird I see a number of warnings in the console. The following line appears many times:

console.warn: Calendar: Message: Error: Property X-ALT-DESC not set


and then I see:

console.error: WebExtensions:

 Message: TypeError: item is null
 Stack:
   deleteItem@resource:///modules/CalStorageCalendar.jsm:362:9

syncEvents@jar:file:///home/user/.thunderbird/9orv369p.default-release/extensions/owl@beonex.com.xpi!/webapi/calendar/calendar.js:833:36


Are these anything to worry about?

In short, no:

  • "-ALT-DESC not set" is just a warning
  • "item is null" happens during sync of the calendar, we try to delete a calendar item that no longer exists. So, that doesn't seem like a problem. Just the error message should be supressed probably.
