Why is my Regex Match returning an array of results instead of one result?

gjuffer

I've created an automation rule that scans the description of an incoming issue for an email address via a regex match, then adds a comment with that email address.  The automation is set up like this:

 

The code looks like this:

@{{issue.description.match("([a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+)")}}

 

This automation successfully finds the email address and adds it to the comment, but it repeats the email twice with a comma separation, such as: 

example@address.com, example@address.com

It seems like the match function is returning an array.  How do I return only a singular email address?

Hi @gjuffer 

I hypothesize that is from how the email is put as markup in the description.  So if it is returning a list, you could get just one value by adding .first or .last to the end of that expression.

Kind regards,
