    /** @var DependencyIndex */

The type Ray\Di\DependencyIndex was not found. Maybe you did not declare it correctly or list all dependencies?

    private $index;

    /** @var bool */
    private $isDefaultAvailable;

    /** @var mixed */
    private $default;

    /** @var string */
    private $meta;

    public function __construct(ReflectionParameter $parameter, string $name)
    {
        $type = $this->getType($parameter);
        $isOptional = $parameter->isOptional();
        $this->isDefaultAvailable = $parameter->isDefaultValueAvailable() || $isOptional;
        if ($isOptional) {
            $this->default = null;
        }

        $this->setDefaultValue($parameter);
        $this->index = $type . '-' . $name;

It seems like $type . '-' . $name of type string is incompatible with the declared type Ray\Di\DependencyIndex of property $index.

        $this->reflection = $parameter;
        $this->meta = sprintf(
            "dependency '%s' with name '%s' used in %s:%d ($%s)",
