Servicenow Script Action not executed

[Anubhuti Mittal]

Hi Team , 

I am working in a scoped application . I have to trigger a script that runs in background when a business rule is fired. For this i have created an event and a script action .

The event is fired from a before update business rule.

The event goes into the processed state but the associated script action is never triggered.

Business rule code 

gs.eventQueue('sn_vul.<BR NAME>',current, 'XX','YY');

@Anubhuti Mittal Did you check if your Script in script action has any syntactical mistakes or the script is crashing. Try to trigger the event via a background script and see if the script triggers if not then try and run the script via a background script and see if it throws any errors.

Hi,
i am also facing the same issue, I have made sure all the above checks. 
My event, BR, Script Action all are in same scope still, event is getting processed but Script action code is not getting executed. 
I am just trying to print log from the script nothing else. 

(function() {

    gs.info("CSSurvey | Survey summary added to incident: ");
})();
tried without function as well
    gs.info("CSSurvey | Survey summary added to incident: ");

Could anyone please guide me what I am missing
