@Jagadeesh Chander ,

What version of Scriptrunner were you using and what version did you upgrade to?

Could be a groovy change or just a breaking change from the plugin.

[Jagadeesh Chander]

we are using Version 7.4 Script runner after upgrading to Jira 9.4.1 it's not working again we tried  degraded version 6.38.0 and also tried it's failing these are all happening after our Jira upgraded to 9.4.1
