Workflow not triggering scoped script

[Chris45]

workflow not triggering scoped script with empty scratchpad after checking out WF, and same error after publishing WF, though previous run works. it looks like scoped script(non Global) IaCloneRollbackWf is not recognized by the WF, error message is not quite helpful, how to troubleshoot such case? any backend log available

Run script activity: 

IaCloneRollbackWf.script.preflightCheck();

error message as below

org.mozilla.javascript.WrappedException: Wrapped TypeError: Cannot read property "script" from undefined (preflightCheck - advanced script; line 1) (<refname>; line 48)

script IaCloneRollbackWf is defined under scope IA Clone, and it worked before checking out WF

sorry but you didn't share any screenshots etc and what are you trying to achieve here?

[Chris45]

Workflow's first activity is preflightCheck, and it calls IaCloneRollbackWf.script.preflightCheck(); when start the WF with given input, it didn't trigger the script, screenshot attached
