Problem/Motivation
With Drupal 11, I have created a Contact Form called "Contact", which has a plain text field for Full Name, a Telephone field, an Email Address field, and an Opt-In Boolean field. I have added this form to a page using the Layout Builder.
I have also installed the SMTP Authentication Support module and configured it to use AWS SES (although the error was the same before I configured this).
Steps to reproduce
Upon submitting the form, I received the following error:
TypeError: Drupal\Component\Utility\Html::escape(): Argument #1 ($text) must be of type string, null given, called in /var/www/html/web/core/lib/Drupal/Component/Render/FormattableMarkup.php on line 238 in Drupal\Component\Utility\Html::escape() (line 431 of core/lib/Drupal/Component/Utility/Html.php).
