Deprecated function: addcslashes() on Preview

Problem/Motivation

The following error occurs when previewing a draft node that contains a webform block (e.g. a contact form or some other webform in a block): Deprecated function: addcslashes(): Passing null to parameter #1 ($string) of type string is deprecated in Drupal\Core\Database\Connection->escapeLike().
