DiscountNode metafield not showing in input query

[cshsusc]

Hi,

I build a shipping discount extension and was following the tutorials to pass the collectionIDs to the input variables.

here is the function configuration for the extension

here is my input query defined:

Here is my discountNode with the metafield in place (in graphiQL):

However in my partners portal I can see that metafield is not returning (or returns NULL).

What am I doing wrong?

thanks
