You need to use parenthesis () instead of braces {}.

Hi Dave,

Sorry I mistakenly used braces instead of a parenthesis. That code above is actually a parenthesis. The one that is failing on my side actually uses a parenthesis, not braces. I will edit the code above to avoid confusions on the people reading my question.

So the issue hasn’t been resolved yet. I wonder if this is a bug or something is wrong on the way I implement it.

Thanks.

Regards,
Reuben
