Calculate hidden fields with JIRA Automation

Question

I want to set a number in the hidden item and calculate it with JIRA automation.
Hiding a field results in a Smart Value Rendering Error.

Is it impossible to calculate a hidden field?

Hi @koutarou ishibashi

Context is important for automation rules; would you please post images of:

* your complete automation rule,
* including where you have that smart value expression, and
* of the audit log details showing the complete rule execution, with that error?

Those may explain the symptom you are observing.  Thanks!

And as Trudy noted from that linked post: "hidden" fields can only be edited by automation rules when the rule actor is the default value, Automation for Jira.  That user has special permissions allowing it to bypass the screen/field checks for edit.  If you have changed the rule actor then it cannot edit / see the field.

Kind regards,
Bill

There is no space after the customfield_.
customfield_10273, if the customfield_10272 is displayed, there will be no error.
customfield_10273, if you hide the customfield_10272, an error will occur.

Can't hidden fields be calculated?

Trudy P Claspill · Answer

The error is not due to trying to set a value on a hidden field. You have syntax errors in your statement that result in Jira not finding the data for the smart values you used.

Your smart values appear to have a blank space between customfield_ and the number that comes next. You need to remove that blank space.
