Jira Automation: how to copy value then remove everything except for numbers?

Chris Case_clbqp6

I have a custom field that contains alpha, numeric, and special characters.

I need to copy the value to a diff custom field then trim out all values except for the numeric characters.

Right now I have it set to trigger when a value is added to the custom field.

Then edit the issue and copy custom field 1 to custom field 2.

I'm then using "Additional Fields to update the copied text to replace all characters except for the numeric.

The Copy function works but when I get to the step to modify the text I get the following error:

Error while rendering additional fields.

Failed to get value for issue.fields.customField_10124.replace('[^0-9]', '')

This is the Additional field data I'm using.

{
"fields": {
"customfield_10124": "{{issue.fields.customField_10124.replace('[^0-9]', '')}}"
}
}

I've tried switching the target and source custom field numbers, and I've tried adding a Re-fetch issue data step but nothing seems to fix it. Thanks for any help you can provide!

Hi @Chris Case

For a question like this, please post an image of your complete automation rule, images of any relevant actions / conditions / branches, an image of the audit log details showing the rule execution, and explain what is not working as expected. Those will provide context for the community to offer ideas. Thanks!

Until we see those...

The replace() function only finds / replace text expressions. To use a regular expression please try using the replaceAll() function: https://support.atlassian.com/cloud-automation/docs/jira-smart-values-text-fields/#replaceAll-String-regex--String-replacement-

And please note: it is not documented for automation rules which parts of the Java spec for regular expressions are / are not supported. I recommend trying simpler expressions first, writing the results to the audit log, and confirming they work as you expect before trying to edit the issue fields.

Kind regards,
Bill

@Chris Case -

Hi Chris:

Try this out in your automation -

Example -

my original string is "Jira Admin IT test 1 please ignore 235"

my smart value used is - "new value - {{issue.summary.replaceAll("[^0-9]","")}}" and I just utilize the "Log action" action to write the output to the audit log. The audit log shows the new value as - "new value - 1235"

Hope this helps. BTW, it is a best practice to get your desired value to output it to audit log for debugging automation rule purpose - https://support.atlassian.com/cloud-automation/docs/debug-an-automation-rule/

Updated to remove text -- meant to add as a reply

Chris Case_clbqp6

Thank you both for your help. First time posting to the community

Here are the screenshots of the rule I've been trying to build out (I've removed the extra steps to refresh data.

Note `customfield_10124` is the target where I'm trying to copy the numeric value to and `customfield_10085` is the source where the alphanumeric value is located.

I just tried again by switching to replaceAll but I don't think I'm using it correctly.

Also tried generating a log action and I'm getting the same error (or looks like it's the same).

For additional context the two custom fields are "Label" type fields if that's helpful or if either of you know if those are not supported. Screenshot 2023-12-28 at 4.46.22 PM.png Screenshot 2023-12-28 at 4.48.31 PM.png Screenshot 2023-12-28 at 4.49.48 PM.png

Thanks for the rule image, Chris.

I see you are trying to use single-quotes within the replaceAll() function, with that then nested within double-quotes for the JSON expression. That will not work: those all need to be double-quotes within the smart value expression.

One work-around for that is to perform the replacement first, saving the value in a created variable. Then use that created variable in the JSON for the advanced edit.

@Chris Case -

Have you try to use double quote instead of single quote?

Let me know of your findings.

Best, Joseph

Chris Case_clbqp6

Huzzah! The combo of using the create variable and using double-quotes fixed it and it's now working

This is what I ended up with - using the Create variable function and replaceALL smart value (with double-quotes) then using that created variable to add to the other custom field. Thank you for your help!

Yes thank you for your help! The double quotes and using the variable was the key to get it to work. I added the automation I ended up with above for reference.
