Undefined property warning

I am getting below the warning message in matomo admin portal. Can anyone help me how to this issue?

WARNING: /var/www/html/matomo/plugins/BeeLikedDBIP/LocationProvider/BeeLikedDBIP.php(64): Notice - Undefined property: stdClass::$continentCode - Matomo 3.13.2 - Please report this message in the Matomo forums: https://forum.matomo.org (please do a search first as it might have been reported already) (Module: UserCountry, Action: adminIndex, In CLI mode: false)


This error occurs in the BeeLikedDBIP plugin, so I’d recommend you to contact the authors of the plugin (GitHub - BeeLiked/db-ip-piwik: DB-IP plugin for Matomo (Piwik) 2.0) or invite them to answer here.
