php - Argument 1 passed to SymfonyComponentValidatorMappingGenericMetadata::addConstraint() must be an instance, string given

Question

When I upgraded the system running Symfony3.0 to version 3.4, the following error occured.
It is a function to change the status in the article to the status selected by pulling down. What else should I consider?

Error Code

Type error: Argument 1 passed to SymfonyComponentValidatorMappingGenericMetadata::addConstraint() must be an instance of SymfonyComponentValidatorConstraint, string given, called in /Symfony/vendor/symfony/symfony/src/Symfony/Component/Validator/Mapping/GenericMetadata.php on line 159
