WebService URL not working for Expense Claim Tutorial Application

Hi All,

I'm creating a K2 Five application by following https://help.nintex.com/en-us/k2five/userguide/5.5/default.htm#Tutorials/Advanced/Expense%20Claim/01Data/04CreateExpClaimCurrencyCodeSmO.htm 

And i could see Current Code URL is not working, by any chance do you have alternate URL or alternate way to achieve this ?
