Use Siri to send whastapp messages is not working.

I am trying to send a whatsapp message by siri. But i am getting error as shown in picture. I tried like this “Hey siri, send whatsapp message to ‘name here’”. But it is always showing error. Why i am getting this error? Could you please help me?

The error message is: I'm sorry, something is not working. Try again later.

Issue just happened with WhatsApp, It does work properly with iPhone message. The problem persist even using Siri at home or from the computer.
