Errors in PHP logs

Hello,
We are seeing lots of error warnings from this plugin in our PHP runtime logs. Please see below examples:
PHP message: Warning: foreach() argument must be of type array|object, null given in /var/www/wp-content/plugins/cf7-conditional-fields/cf7cf.php on line 543 [URL_REMOVED/wp-json/contact-form-7/v1/contact-forms/278/feedback?_locale=user] [wp-includes/class-wp-hook.php:308 {closure}(), wp-includes/plugin.php:205 WP_Hook->apply_filters(), wp-content/plugins/contact-form-7/includes/rest-api.php:359 apply_filters(‘wpcf7_feedback_response’), wp-includes/rest-api/class-wp-rest-server.php:1181 wpcf7_rest_create_feedback(), wp-includes/rest-api/class-wp-rest-server.php:1028 WP_REST_Server->respond_to_request(), wp-includes/rest-api/class-wp-rest-server.php:442 WP_REST_Server->dispatch(), wp-includes/rest-api.php:410 WP_REST_Server->serve_request(), wp-includes/class-wp-hook.php:308 rest_api_loaded(), wp-includes/class-wp-hook.php:332 WP_Hook->apply_filters(), wp-includes/plugin.php:565 WP_Hook->do_action(), wp-includes/class-wp.php:399 do_action_ref_array(), wp-includes/class-wp.php:780 WP->parse_request(), wp-includes/functions.php:1334 WP->main(), wp-blog-header.php:16 wp(), index.php:17 require(‘wp-blog-header.php’)]

We are currently using Contact Form 7 version 5.4 and Conditional Fields for Contact Form 7 version 2.3.7 on WordPress 6.2 PHP version 8. Can you please let us know what’s needed to fix the warnings?
