Hello everyone, I’m having a curious error. I’m setting up the bounces on the mautic. The mautic connects in the inbox without problems, but when will run the cron down to mark the contacts as “do not contact”

[Symfony\Component\Debug\Exception\ClassNotFoundException]  
Attempted to load class “Type” from namespace “Mautic\EmailBundle\MonitoredEmail\Processor\Bounce”.  
Did you forget a “use” statement for e.g. “JMS\Serializer\Annotation\Type”, “Doctrine\DBAL\Types\Type”, “Aws\DynamoDb\E  
num\Type”, “Symfony\Component\Validator\Constraints\Type” or “Mautic\EmailBundle\MonitoredEmail\Processor\Bounce\Defini  
tion\Type”?
