Issue Summary

When trying to create an automation rule to split the page title and create them as labels the split parameter is not working and no label is published.

Steps to Reproduce

1. Create a rule to publish a page
2. Add a condition to add label upon page publish with this condition {
   Unknown macro: {page.title.split(" ")}

   }

Expected Results

The labels should be created as expected, for example the page title is "Test automation" there should be two labels created "test" and 'automation"

Actual Results

No label is created.

Workaround

Please use the page.title  smart value to create a label with the page title without splitting.
Currently there is no known workaround for this behavior. A workaround will be added here when available
