Trying to use smart values to update labels for due date

Tyler Tate

I am at my wit's end here. I have been trying to write a very simple automation that can update an issues label when its due date has been changed. The format is MMMM-yyyy for the label based on due date. All I want to do is if an issue has its due date updated that 1 of 2 things will happen.

Let's say due date is 9/1/2024. 

1. If no due date exists then that's really easy to add a new label for that. 

2 (where I'm stuck). Let's say that I already have a label of September-2024 but now my due date update to 10/7/2024. I want a new label of October-2024 to be created and old label of September-2024 to be removed. 

I was doing a basic When: Value changes for Due date Then edit issue fields Labels. 

Adding a new label works fine with: 

{{issue.duedate.format("MMMM-yyyy")}}

but where I'm struggling is removing the old. I've tried the below but I can't seem to figure out what I'm missing. 

{{issue.labels.match("^(January|February|March|April|May|June|July|August|September|October|November|December)-\\d{4}$")}}

{{issue.duedate.change.previous.format("MMMM-yyyy")}}

Any help to point me in the right direction would be great!

Hi @Tyler Tate, welcome to Altassian community.

You should treat labels as a list by using the syntax as described here Jira smart values - lists | Automation for Jira Cloud and Data Center | Atlassian Documentation

{{#labels}} {{/}}

Secondly, do not try to change the label found, but first remove it from the list and then you add the new label. 

Hope this guide you in the right direction. 

EDITED:

A simpler approach that you might try is something like this:

Use ADDREMOVE option when editing the Labels field (ref yellow).
