Populating a custom field with a substring from Summary

[Vinicius Zhu]

I have a custom field I want populated with a piece of my Summary. I wrote a regex to help me doing that, and I validated it here.

(PRJ|INC|PRB|RITM|TASK|VUL|CHG|\wTASK)(\d+)

I created an automation rule, triggered whenever an issue is updated, trying to match this regex in my summaries:

And it works. Not only I see the SUCCESS status in Audit log, but also, I see the issue being updated by the rule:

However, the rule itself isn't updating the issue the right way. Here is how I set the rule (I tried not using the "additional fields" and choosing my custom field on the above dropdown instead, but got the same results). This is the update rule:

And this is the result I get:

Apparently, even though the "comparison regex" matches the entire Ticket Number (PRB1234567), the "update regex" gets only the first characters and ignore the numbers.

Any hints?

Thank you!

@Vinicius Zhu, you're really close! One modification is all you need. Wrap the two capture groups in another set of parens.

{{issue.summary.match("((PRJ|INC|PRB|RITM|TASK|VUL|CHG|\wTASK)(\d+))")}}
