Receive only first instance of match

Nadege_l19417

I am trying to create an automation that stores an issue key found within a comment. Currently I have the following:

 

ABC-{{comment.body.match("ABC-(\\d{1,6})")}}

 

Not sure why, but it sends the code twice e.g ABC-1234, 1234

It seems like it is writing down the same match twice (it is from a link so not sure if that affects).

Is there a way to prevent this so that I have ABC-1234 only? Thanks

Hi @Nadege 

You appear to be extracting issue keys from a comment body.  There are several things to handle for that scenario:

First, the match() function can have difficulty with comment formatting, such as newlines.  Thus it makes sense to parse those out first, perhaps by using the replace function to convert them to spaces.

Next, your comment likely contains a smart link, and so a specific issue key could be found multiple times.  That could be reduced using the distinct function: https://support.atlassian.com/cloud-automation/docs/jira-smart-values-lists/#list.distinct

Finally, are you certain your comment contains one-and-only-one issue key?  Perhaps it could contain several.

Putting those together, this expression would return the distinct keys found in the comment.  

{{issue.comment.last.body.replace("\n", " ").match("([A-Z]+-\\d+)").distinct}}

 

Kind regards,
Bill
