Error in 2.0.4 on local (Windows) WP Environment

Starting with version 2.0.4 of Advanced WP Reset I get an error after opening Tools => Advanced WP Reset in local http (not https) WP environments on Windows (Laragon + Local):

Warning: Trying to access array offset on value of type null in …\wp-content\plugins\advanced-wp-reset\js.config.inc.php on line 43 (+ 44, 45, 46)

Checked as:

$message_array['awr_pro_url'] = $popup_infos['link'];
$message_array['awr_pro_text'] = $popup_infos['text'];;
$message_array['awr_pro_offer'] = $popup_infos['offer'];
$message_array['awr_pro_offer_message'] = $popup_infos['offer_message'];
