after downloading the sdk through composer(PHP) and doing the neccessary things, I run nto this problem
Fatal error: Declaration of JMS\Serializer\JsonDeserializationVisitor::startVisitingObject(JMS\Serializer\Metadata\ClassMetadata $metadata, JMS\Serializer\object $object, array $type): void must be compatible with JMS\Serializer\Visitor\DeserializationVisitorInterface::startVisitingObject(JMS\Serializer\Metadata\ClassMetadata $metadata, JMS\Serializer\Visitor\object $data, array $type): void in /home/vagrant/Code/Project/vendor/jms/serializer/src/JsonDeserializationVisitor.php on line 14
What does it mean and how can I solve the problem
Please provide us with more details on the version of PHP-SDK you are using.
Did you do a fresh setup with composer or did you upgrade your setup from previous version of sdk to the current one ?
Also sharing the OS and PHP version information would help us while looking into this issue.
