Workflow Post Function transition is not working when using Condition

Xporter isn't working properly with Workflow Post Function transition when users have defined Conditions.

Steps to reproduce the error:

• Install the version 5.7.4 on your JIRA instance
• Create a new Workflow Post Post Function Multi-Action, for example
• Define a new condition
• Try to perform the transition

Error:
The error is related to the regex used to evaluate the condition.

Condition:

"${Key}".equals("DEMO-23")
