Thank you @solantoast #11 works very well.

I have committed 🐛 InvalidArgumentException: The timestamp must be numeric. in Drupal\Component\Datetime\DateTimePlus::createFromTimestamp() (line 201 of /var/www/html/www/core/lib/Drupal/Component/Datetime/DateTimePlus.php). Active (including a test). I think its the same issue.

Automatically closed - issue fixed for 2 weeks with no activity.
