Warning Invalid argument supplied for foreach

There is a warning showing up, in our logs, most probably due to not having a is !is empty condition before the foreach at line 305, can you post an update for this in the next version?

PHP Warning: Invalid argument supplied for foreach() in /site path/wp-content/plugins/wp-residence-add-on-for-wp-all-import/wp-residence-add-on.php on line 305, referer: https://site-url/wp-cron.php?import_key=M7bEGNJbV2&import_id=19&action=processing&1861168234

Thanks!
