Error updating status through Scriptrunner

[Bhanu Priya KS]

Hi,

I have written a script to  extract claim numbers and then if there is a single unique claim number, update the status on the issue. But when I try to execute the script, I get the below error. 

The claim number updates in the field when I remove the logic to update the status and the code for updating the status runs perfectly fine when I run it on the console. But the problem arises when I run this as part of an automation rule triggered when issue is created.  Can you please help with what I am doing wrong?

"Script function failed on Automation for Jira rule: Read and set Claim Number, Issue Type, file: <inline script>, No signature of method: com.atlassian.jira.issue.managers.RequestCachingIssueManager.call() is applicable for argument types: () values: [] Possible solutions: wait(), any(), wait(long), each(groovy.lang.Closure), any(groovy.lang.Closure), tap(groovy.lang.Closure)"
