Trying to extend bundled example to work with object, I'm not able to get value. Consider following code:

$isolate = new \V8\Isolate();
$context = new \V8\Context($isolate);
$source = new \V8\StringValue($isolate, "var say = function() {return {foo: 'bar'};}; say();");
$script = new \V8\Script($context, $source);
$result = $script->run($context);
echo $result->value() . PHP_EOL;

I understand that return value is no longer StringValue but ObjectValue instead. How do I properly get it's value?

My use-case is rendering VueJS app on server to implement server side rendering. For this, I need to execute some wrapper javascript and app itself on the server. This js code results in ObjectValue just like my example above. If I try to do $result->toString($context)->value() I get [object Object] which is not usable. What is a correct way to do this?
