When a ApiPlatform\Validator\Exception\ValidationException is created with a ConstraintViolationList and a $previous exception, the current constructor breaks on

core/src/Validator/Exception/ValidationException.php

Line 76 in 67fbe51

parent::__construct($code ?? $this->__toString(), $previous ?? 0, $errorTitle instanceof \Throwable ? $errorTitle : null);

with the following error:

TypeError: Exception::__construct(): Argument #2 ($code) must be of type int, Exception given
