New Fields Country Code appearing in Zapier

I am looking a recent failure in our Zap runs when we map the fields

If you see, Invoice Ninja now needs a Country Code instead of Country to create a new user - which is causing the issue.
We were earlier using the CRM equivalent of country instead of the Country Code and it was working fine. Somewhere down the line I think the mandatory field has changed to Country Code and is causing the failure.
Can you please recommend a solution here?

country_code is the correct field, but it appears you are sending in duplicated codes? SA,SA

The point is why have country code - Why not a country field instead?


Not sure I follow, we have country_id available if you want to use the countries table that we store, OR we provide these convenience fields when you need to use iso 3166 -2/3
