Issue Summary

The customer has recently upgraded from Jira 10.3.11 to 10.3.12, after which they were no longer able to set an Automation for Jira variable to a new value which refers to the previous value of the same variable.

Steps to Reproduce

1. Create an automation rule with the following components:
   When: any trigger
   Then: Create variable testvariable with the value testvalue1
   And: Create variable testvariable with the value {{testvariable.replaceAll("testvalue1", "testvalue2")}}
   And: Add value to the audit log with the log message {{
   Unknown macro: {{testvariable}

   }}}

1. Trigger the automation rule.

1. Observe that in Jira 10.3.11, testvalue2 is logged, but in Jira 10.3.12, an empty string is logged.

Expected Results

In Jira 10.3.12, the updated value should be logged. 

Actual Results

In Jira 10.3.12, an empty string is logged.

Workaround

In the meantime the workaround will be to create the temporary variable to store the result
