    public function greet(string $name): \Generator
    {
        $version = Workflow::getVersion('test', -1, 1);
        if ((int) $version === -1) {
            return yield $this->greetingActivity->composeGreeting('Hello', $name);
        } else {
            yield Workflow::sideEffect(fn() => 'test');
            return '1';
        }
    }

Workflow::getVersion() returns a promise
You should use yield with it.
