Magento Open Source 2.4.5
I am having issues with emails. They are coming through without the email body content and just "We're sorry, an error has occurred while generating this content."
The following is from our system.log:
InvalidArgumentException: Unable to serialize value. Error: Malformed UTF-8 characters, possibly incorrectly encoded in public_html/vendor/magento/framework/Serialize/Serializer/Json.php:26
