App: "Automation for Jira - Data Center and Server" error

[jiangyu]

I download this application from this url :

https://marketplace.atlassian.com/apps/1215460/automation-for-jira-data-center-and-server?hosting=datacenter&tab=overview

when I run my  automatic rule , it appears the following error:

I installed the latest version and old version, always error when run rules. 

I have no idea how to solve this problem. it seems that the problem caused by the application itself?
