Adobe campaign client console Message center coupons

Hi All,

How can we use coupon management [nms:coupon] in the message center emails. Below are the steps i have followed:

1. Uploaded the coupons to coupon management -> 2. Checked coupons are already present and are correctly imported -> 3. Used these coupons under "coupon management" tab of a Message center email -> 4. Tried sending a proof -> Below Error received 

Coupon used in the html as :  <%= couponValue.couponCode %>

=> Above steps are working perfectly fine for any normal campaign but fails for Message center emails.

Is there a way, we can use coupons uploaded via coupon management system in transactional message center emails?

Any help is highly appreciated. Thank you in advance!
