Is there a way to extract a URL from the last comment and then edit a custom field to include that?

[Phil Jones]

So I'm stepping into an environment where a request has been around for a while to have a URL extracted from the last comment and adding it to a URL custom field. 

I've added the custom field (URL Field), I've created an automation that conditions to look for a regex that includes the URL we need (domain.atlassian.net). However I'm running into issues adding an action with a smart value to extract that URL that the condition is checking for. 

The condition I'm using a smart value checker to look for a regex pattern in the last comment.

However, in creating the variable I'm trying to use something along the lines of: 

{{comment.last.body.match(regexpattern)}}

When I have it update the log, the log is empty. 

Any help would be greatly appreciated!

If the custom field is available, why can't the user just put in the URL straight into the field?

Additionally, you could create a screen that pops up when you transition an issue that then displays the URL custom field?  And if needed, you can make that field be required before you can transition.  Just a thought because going down and thinking about regex patterns frightens me =)
