Count times a string appears in a label

Question

Hello, I'm trying to count how many dates of format

YYYY_Tx

exist in a Labels field and save this as a numeric value in another field. I try the below, but I keep getting erros. Any help on what is wrong? So the Labels has: 2024_T3 , 2025_T1 , etc

The error I get:

Unable to render smart values when executing this rule:

Failed to get value for issue.Labels.match('.*(\d{4}_T\d).*').size: { "fields": { "Overall effort": "{{issue.Labels.match('.*(\d{4}_T\d).*').size}}" } }the expression I put in the edit issue field (to update the Overall effort numeric field): { "fields": { "Overall effort": "{{issue.Labels.match('.*(\d{4}_T\d).*').size}}" } }

Hi @Menia Laina

To count how many labels in the format YYYY_Tx exist in your Labels field and save the count in another field, your current smart value expression is close but has a slight issue.

The Fix

The match function is being applied incorrectly in your smart value expression. Instead of using .match to count occurrences, you should use .filter to isolate the labels matching the desired format and then count them using .size.

Here’s the corrected expression:

{
"fields": {
"Overall effort": "{{issue.labels.filter(label -> label.match('\d{4}_T\d')).size}}"
}
}

Explanation

* issue.labels: Refers to the Labels field, which is a list of strings.
* .filter(label -> label.match('\d{4}_T\d')): Filters the labels, keeping only those matching the format YYYY_Tx using a regex pattern.
* .size: Counts the number of matching labels.

Steps to Implement

* Edit your automation rule.
* Use the above expression in the "Edit issue" action for updating the Overall effort field.
* Test the rule with sample data to ensure it works as expected.
