Is there a way to skip a data when a domain doesn't contain a specific variable

I'm really confused on how to bypass this problem from whois, is there a way so that when whois outputs the domain variable and it doesn't contain the specific variable that i want to showcase, it would just skip it instead of giving me an error?

This is the error that i got when inside the array list doesn't contain any emails variables.
