exception handling in business rules

[Rajesh Sheela1]

I have created one business rule which creates incident automatically when case submitted for one subcategory. But i need to handle exception handling in that business rule. Can anyone help me how to achieve this?

Business rule: is 

When to Run : After insert

Script is below :

(function executeRule(current, previous /*null when async*/) {

ProductSecurity();
})(current, previous);

function ProductSecurity(){
var psInc=new GlideRecord("incident");
psInc.initialize();
psInc.short_description=current.short_description;
psInc.description=current.description;
psInc.caller_id=current.contact;
psInc.u_asset=current.asset;
psInc.u_account=current.account;
psInc.u_product=current.product;
current.impact='1';
current.urgency='2';
psInc.contact_type=current.contact_type;
psInc.contract=current.contract;
psInc.u_entitlement=current.entitlement;
psInc.u_ci_service_level=current.u_ci_service_level;
psInc.category=current.category;
psInc.subcategory=current.subcategory;
psInc.insert();
gs.addInfoMessage(gs.getMessage('Product Security Incident - ' + psInc.number + ' is created'));
current.incident=psInc.sys_id;
current.update();
}

Hi @Rajesh Sheela1 ,

Wrapping all code in try/catch blocks or move your code to script include and use try/catch blocks

Example:

try{ 
         // Put code here in case something goes wrong.
} catch(e){         
      //Use any one of the below methods to log the error message.
         gs.error(e.message);
         gs.addErrorMessage('Exception throw while biting apple:'+e.message);
         gs.addInfoMessage('Name of module where error happened:'+ e.message);
}

Hello @Rajesh Sheela1 

If you want exception handling then you can use the try(), catch() block as shown in below script:

Also instead of After Insert BR try once with Async Insert BR. Because it is not recommended to use current.update() in After BR.

In your code since you have created the function ProductSecurity() outside the function executeRule() and you have not passed any parameter while calling the function ProductSecurity() the current and previous object will not be accessible in ProductSecurity() function.

(function executeRule(current, previous /*null when async*/) {
try {
    var psInc=new GlideRecord("incident");
    psInc.initialize();
    psInc.short_description=current.short_description;
    psInc.description=current.description;
    psInc.caller_id=current.contact;
    psInc.u_asset=current.asset;
    psInc.u_account=current.account;
    psInc.u_product=current.product;

    psInc.contact_type=current.contact_type;
    psInc.contract=current.contract;
    psInc.u_entitlement=current.entitlement;
    psInc.u_ci_service_level=current.u_ci_service_level;
    psInc.category=current.category;
    psInc.subcategory=current.subcategory;
    var psIncID = psInc.insert();
    if (!psIncID) {
         gs.addErrorMessage("Product Security Incident is not created");
    } else {
         gs.addInfoMessage(gs.getMessage('Product Security Incident - ' + psInc.number + ' is created'));
        current.impact='1';
        current.urgency='2';
        current.incident=psInc.sys_id;
        current.update();
    }
  } catch(e) {
    gs.addErrorMessage(e);
  }
})(current, previous);
