Update Notifier error after upgrade 10.0.1 -> 10.0.2

After successfully updating my nextcloud to version 10.0.2 the update notifier doesn’t stop telling me that there is an update availlable.
Error Log shows this line:
Error PHP Undefined index: version at /var/www/nextcloud/apps/updatenotification/lib/Notification/Notifier.php#72
Administration panel shows the correct version and says thatthere are NO updates for my nextcloud . I’m on stable channel.
What went wrong?
