Problem Statement:

Automation for JIRA throws errors when using variables to capture Label values, performing actions on the values fetched(Eg: Converting to Uppercase), and then adding it back to a Label field.

How to Reproduce:

AUTOMATION RULE:

Trigger: Issue Created
Then: Create Variable = Upper
Upper = issue.fields.customfield_xxxx.toUpperCase()
And: Edit Issue Fields: customfield_xxxx = Upper

ERROR:

Edit issue
Error editing issues
Proj-xxxx (The label 'JIRA AUTOMATION' can't contain spaces. (customfield_xxxx))

CAUSE:

• When adding/setting the labels field on an issue through automation, it currently assumes that a smart value will resolve to a single value.
• If you are trying to add multiple labels through automation by assigning values to a label field through a variable, It will resolve the multiple labels into a single value. It is considering the "space" in between the labels and making it a single value and you will end up with the error "The label X can't contain spaces" in the automation audit log.

WORKAROUND:

Currently there is no known workaround for this behavior. A workaround will be added here when available.
