Submitting an empty form php notice

[afatoga]

Issue Overview

Recently I encountered a php notice after submitting an empty form within my production version of an app. Though when I tried to reproduce the same behavior at my localhost - everything ran fine.

Other functions within the production version are correct.

Notice: Array to string conversion in /data/web/virtuals/224154/virtual/www/wp-content/plugins/torro-forms/vendor/felixarntz/plugin-lib/src/db-objects/model.php on line 546

Steps to Reproduce (for bugs)

1. Create a form
2. Open a link with a form
3. Submit an empty form

PHP 7.3
MariaDB 10.4.6

Expected Behavior

It should show warnings about empty fields.

Current Behavior

Form is not submitted. User has to reload a page with F5.

I managed to "solve" the problem by disabling wp_debug in wp-config.php. Then the notice was skipped and correct response appeared. Though it's kind of faking...
